Oil paint is a thick, colorful paste artists use to create long-lasting pictures. The type of oil paint you pick can shape your art. There are two main grades: artist-grade and student-grade.
Artist-grade uses pure pigments, so the color glows and covers well. It’s not cheap—some tubes cost $40 or more! Student-grade uses more fillers and costs less, about $7 per tube.
Well-known brands include Old Holland (making paint since 1664 with 168 colors), Williamsburg (over 170 colors in small batches), Michael Harding (100 colors since 1982), Gamblin (made in Portland using special linseed oil), and M.
Graham (from Oregon, no harsh solvents). Each brand fits different needs for beginners or pros.
How do you choose? Check the pigment load, how long it lasts without fading, how smooth it spreads, and if it mixes well with titanium white. Premium hues like Cadmium, Cerulean Blue, Cobalt Blue—or Lapiz Lazuli—cost even more due to rare minerals inside.
If you’re just starting out, student lines from Winsor & Newton work fine for practice—you might want burnt umber or titanium white on day one. As your skill grows, you can try paints packed with richer pigment.
Gamblin stands out because artists love their balance between price and quality; plus their Reclaimed Earth Colors Set gives cool options with less mess—and often a 25% sale!
As a beginner painting at home or an expert working on big projects—for fun or fine art—your palette should start simple: basics like Cadmium Yellow Medium or Ultramarine Blue help everyone learn color mixing fast.
Classic oil paint blends smoothly but takes weeks to dry; water-mixable ones clean up easy for quick results or eco-friendly studios. You keep oils fresh by freezing them to -20°C or sealing them tight with clove oil drops—a neat trick!
Choosing the right oil paint shapes every picture you make… So let’s break down what matters most before you dip that brush into color!
Key Takeaways
- Oil paints come in two main types: artist/professional grade and student grade. Artist-grade paints have pure pigments, richer colors, and last longer. They can cost $15–$50 per 40ml tube (sometimes up to $40+), with brands like Michael Harding and Old Holland. Student-grade paints are cheaper, about $4–$15 per 40ml tube, but use more fillers; examples include Winsor & Newton Winton or Gamblin 1980.
- Choose paint based on your purpose and budget. Beginners or young artists (ages 10–17) often start with student-grade for practice because it costs about 60% less than professional tubes. Advanced students or pros pick artist-grade for artworks meant to be sold or shown in galleries.
- Key factors when buying oil paint are pigment quality (high pigment load means bright hues that last), price (balance value against how much you want to spend), and the artwork’s goal—fine art vs practice pieces. Good brands list “lightfastness I” or “ASTM I” which shows paintings will resist fading over time.
- Top oil paint brands include Michael Harding, Old Holland, Williamsburg Handmade Oils (USA-made; small traditional batches of just five gallons at a time), Gamblin from Oregon (offers safe options like Gamsol solvent), and M. Graham Oils (solvent-free). Prices range widely—from under $11 for small tubes up to over $600 for large sets.
- Start with a simple palette: key colors like Cadmium Yellow Medium, Alizarin Crimson, French Ultramarine Blue, Burnt Sienna, Ivory Black, and Titanium White cover most needs for beginners. Artists can later expand their set using advanced colors such as Lapiz Lazuli blue or Naphthol Red according to their style and project goals.
Understanding Oil Paint Grades

Oil paints come in two main types: artist grade and student grade. Artist grade paints have high-quality pigments. They give rich colors that last a long time. Student grade paints are cheaper and good for practice.
They’re okay for learning, but they don’t always mix well or hold up like the professional ones do.
So, if you’re doing serious work, go for artist grade… But if you’re just starting out or trying new styles, student paint works just fine!
Artist/Professional Grade vs. Student Grade
Sure, so here’s how the match-up between Artist/Professional Grade and Student Grade oil paints shakes out… quick table style, because sometimes you just want the facts (and a little personality).
| Feature | Artist/Professional Grade | Student Grade |
|---|---|---|
| Pigment Quality |
– Uses pure pigments – Highly saturated colors – Minimal fillers – Example: Michael Harding, Old Holland, Williamsburg |
– More fillers or binders – Lower pigment load – Colors less intense – Example: Winsor & Newton Winton, Gamblin 1980 |
| Color Names |
– True pigment names (Cadmium Red, Ultramarine Blue, etc.) – No “Hue” trickery |
– Many “hue” substitutes (Cobalt Blue Hue instead of Cobalt Blue) – Some shift as they dry |
| Price Point |
– Can be up to 10 times more expensive than student grade – Usually $15–$50 per 40ml tube – Made for artists selling work |
– Two to three times cheaper than artist grade – Around $4–$15 per 40ml tube – Made for practice, learning, or tight budgets |
| Performance |
– Smooth, buttery texture – Superior blending and coverage – Higher lightfastness – Pigments stay bright longer |
– Quicker drying – Less coverage, some streakiness – Color may fade or shift with time |
| Best For |
– Professionals – Serious hobbyists – Work meant for sale or galleries |
– Beginners – Hobbyists – Classroom use – Practicing new ideas |
| Brands |
– Michael Harding – Old Holland – Williamsburg – Gamblin Artist Oils – M. Graham Oils |
– Winsor & Newton Winton – Gamblin 1980 – Daler-Rowney Georgian – Van Gogh |
| Lightfastness (How long color lasts) |
– Very high – Made to last for decades |
– Can be lower – Best used for studies or short-term displays |
You can spot the “pro” stuff by price and pigment names, while the “student” stuff usually tags on “hue,” dries fast, and feels a bit more, well, basic. If you want those colors to pop in a museum someday, you’re looking at professional grade. If you want to save cash and experiment, student grade is the way to go (just don’t expect miracles for four bucks a tube). Some big players, like Winsor & Newton, sell both kinds, so you can mix and match as you level up.
When to Choose Each Grade
Moving from “Artist/Professional Grade vs. Student Grade,” you might ask, “Which oil paint grade should I grab for my next masterpiece… or doodle?” It’s not about snobbery—just the right tool for your stage and use.
New painters, especially kids and teens (ages 10-17), often pick student-grade oil paints because they cost about 60% less than artist-grade tubes. Student brands save money with more binder and fewer high-quality pigments—think burnt sienna or titanium white without emptying your wallet on day one.
If you’re serious or plan to sell work, professional grade makes sense. Artist oils carry more pigment (yep, that means richer color mixing). Fine art schools in places like New York or Los Angeles recommend advanced students start shifting to premium lines once basic skills are set.
Grab primaries in artist quality—like cadmium yellow, phthalo blue, and alizarin crimson—and mix everything else with them if budgets get tight (I’ve been there… single tubes can hit $40 each).
Hobbyists or those practicing plein air painting outside usually stick to mid-price sets until ready for bigger steps; professionals go all-in on top brands such as Old Holland Oils or Michael Harding Oil Paints so their vibrant colors last long-term on gallery walls.
Start cheap so mistakes don’t sting; switch up as your skill grows.
Factors to Consider When Selecting Oil Paints
When choosing oil paints, think about some key points. Quality matters a lot—look for colors with high pigment levels that give bright, vibrant hues.
Price is also crucial. You want to balance your budget without sacrificing value. Consider what you’ll use the paint for too—are you making art or just practicing?
Quality: Pigment Load and Permanence
High-quality oil paints use more pure pigment and less filler. You get bright, strong colors like cadmium red or cobalt blue. Artist-grade paints, like Old Holland or Michael Harding, pack a higher pigment load.
This makes your colors last longer and stand out better on the canvas. Cheaper, student-grade paints add fillers, so the color feels weak and can fade over time.
Always check the permanence rating. Good brands list this on the tube. Look for labels showing “lightfastness I” or “ASTM I.” These marks mean your paintings will not fade or change, even after 100 years.
Some brands like Winsor & Newton or Gamblin have been tested in different climates for years. High pigment loads and strong permanence mean smoother blending, bold colors, and art that stays bright.
That’s why professionals trust brands with no fillers and the best lightfastness standards.
Price: Balancing Budget and Value
Quality matters, but price also plays a big role in your choice of oil paints. Artist-grade oils are usually more expensive than student-grade ones. A good tube can cost between $7 and over $40.
Sure, that sounds steep, but these high-quality paints have a richer pigment load. This means you’ll need to use less paint to get the same vibrant colors in your art.
For beginners or those on a budget, student-grade oils offer decent quality without breaking the bank. They provide enough value for practice and experimentation until you’re ready to invest in better options.
Brands like Gamblin have affordable lines perfect for new artists. Advanced artists should think about spending more on premium brands like Old Holland or Winsor & Newton if they want their work to last longer and look stunning.
Choosing the right paint is about finding what fits your style and wallet.
Purpose: Fine Art, Practice, or Experimentation
The purpose of your oil paints matters a lot. If you aim to create fine art, choose professional-grade oil paints. These have high pigment loads and great permanence. They help make stunning artworks that can be sold or shown in galleries.
For practice or experimentation, student-grade oils are the way to go. They cost less but still perform well enough for your studies. You can try new techniques without worrying about wasting your money on expensive colors (we all hate that).
Using lower-cost paints during skill development allows more freedom to explore.
Keep in mind what you want from the paint. Are you working on a finished piece? Go with professional-grade options for better results. For casual projects or studies, student grades work just fine!

Traditional vs. Water-Mixable Oil Paints
Traditional oil paints use linseed, safflower, or walnut oils as their base. These paints give you rich colors and a slow drying time—perfect for blending. Water-mixable oils, on the other hand, mix with water instead of thinner (goodbye strong smells!).
They dry faster and are easy to clean up… so a lot of artists love them!
Benefits of Traditional Oil Paints
Traditional oil paints bring thick, vibrant colors to your artwork. They have a rich pigment load that gives excellent covering power. You will notice how these paints create smooth blends and soft effects in your paintings.
The drying time for traditional oils is about two days to become touch-dry, but thicker layers may take months or even years. This slower drying time allows you to blend and layer your colors effectively.
These paints also provide a beautiful sheen once dry. A slight shine can enhance the visual depth of your work. Many artists find that traditional oil paints outperform water-mixable options for certain techniques and styles.
These high-quality pigments often include rare and historical options, adding a unique touch to your art piece. If you are serious about painting, choosing traditional oils could be the way to go!
Advantages of Water-Mixable Options
Water-mixable oil paints come with many perks. They mix easily with water, making cleanup a breeze. You won’t have to deal with harsh chemical smells either. This is great for artists who are sensitive to odors or work in shared spaces.
These paints dry faster than traditional oils. Many become touch-dry in about an hour! If you like to finish projects quickly, this option is perfect for you. Plus, they blend smoothly without disturbing other colors underneath.
Layering becomes much easier as well.
You will find that water-mixable oils are often cheaper too because they contain less pigment. They also support eco-friendly practices compared to regular oil paints. Using these allows you to enjoy your art while feeling good about the environment around you! Next up: exploring tips for maximizing your oil paint investment.
Tips for Maximizing Your Oil Paint Investment
To protect your oil paints, store them in a cool, dark place. Keep the lids tight to prevent drying out… (trust me, you don’t want that!). Use proper thinners like odorless mineral spirits for mixing and cleaning.
They help your paint last longer and work better!
When blending colors, try adding high-quality pigments slowly. This way, you can create vibrant hues without wasting paint—no one likes wasting good stuff!
Proper Storage and Handling
Store your oil paints properly to keep them fresh. Cover palettes with plastic wrap and put them in the freezer, but only if you are using linseed oil; it needs to be at -20°C. Transfer unused paint into airtight containers.
This limits air exposure and prevents drying out.
Use a glass palette to maintain moisture longer. Hang tubes of paint upside down with binder clips, so the nozzle stays clear. Keep your supplies in a cool, dark place between 10°C and 20°C (50°F-68°F).
Avoid direct sunlight for better long-term storage. Clean caps often to prevent buildup on your tubes. To save every drop of paint, roll up from the end of the tube or use a tube wringer carefully! Add drops of clove oil while working to extend drying time on your palette too!
Mixing and Blending Techniques
Start with white paint. Titanium White is a great choice because it helps in mixing colors. The opacity of your oil paints matters too. It can be opaque, semitransparent, or transparent.
You can find these ratings on the tubes.
Mixing primary colors like blue, red, and yellow creates many other colors. When you blend well, your painting looks more real and has depth. Use palette knives or brushes for blending; each gives a different look.
The “fat over lean” rule is key for layers. This means using more medium in top layers than in bottom ones to avoid cracking as they dry. Using linseed oil or turpentine can help improve consistency and speed up drying too! Practice makes perfect; keep trying until you find what works best for you!
Conclusion
Choosing the right oil paints can make a significant difference in your artwork. You learned about different grades of paint and when to use each one. Quality matters, so select paints with high pigment for the best results.
It’s also wise to check prices and your budget before buying; good oil paints can range from $7 to over $40 per tube. For extra assistance, explore videos on YouTube about oil painting supplies or read up on color palettes and brushes that suit you.
Great tools lead to amazing art!
FAQs
1. What should I look for when picking oil paints for different painting techniques?
Look at paint consistency, drying time, and pigment quality. Some brands use high-quality pigments that give vibrant colors perfect for both classic and modern oil painting techniques.
2. Are there big differences between student grade and professional grade oil paints?
Yes, student grade has less pigment and more filler; it is cheaper but not as bright or rich in color. Professional grade uses better binding agents like linseed oil or walnut oil, giving you stronger color harmony and smoother colour mixing.
3. Which oils work best as a binding agent in oil paints?
Linseed oil is common because it dries well and keeps the paint strong. Safflower oil gives softer whites like titanium white while walnut oil helps with smooth blending. Some artists try stand oil or even flaxseed to change texture.
4. How do I choose the best colors for a limited palette?
Start with basics: burnt sienna, yellow ochre, cadmium red, cadmium yellow, cobalt blue hue (or just plain cobalt blue), brown ochre, plus titanium white. This set covers most needs whether you are plein air painting outdoors or working inside.
5. Why does drying time matter in choosing your supplies?
Paints made with safflower or walnut oils dry slower than those using linseed oil so they let you blend longer on canvas (which can be great if you keep changing your mind). If you want faster results though go with quick-drying options from top art supply brands like Winsor & Newton or Michael Harding.
6. Can I mix acrylic paint with my oils to save money on art supplies?
Nope! Acrylic painting uses water-based materials so they do not mix well with traditional oils which need odourless mineral spirits for cleaning up brushes (trust me I tried once…it was a mess). Stick to one type per project unless you love chaos on your palette!
