Quick Answer
A useful oil paint color mixing chart starts with a limited palette, not every tube you own. Use warm and cool primaries, titanium white, and one earth color. Then chart mixtures in small, labeled steps so you can see hue shift, value shift, chroma loss, and drying behavior before you commit paint to a canvas.
An oil paint color mixing chart is only helpful if it changes how you paint.
A pretty grid of orange, green, and purple can look satisfying. But if the chart does not tell you which blue makes cleaner greens, which red muddies fastest, how much white kills saturation, or when a metallic tube should stay out of a base mix, it becomes studio wallpaper.
This guide builds a practical chart. The kind you keep near the easel because it answers small, expensive questions before you squeeze out more paint.
Start With The Right Palette, Not The Biggest Set
The best beginner oil paint mixing chart uses two versions of each primary: one warm and one cool. This gives you cleaner secondary colors and makes dull neutrals easier to control. Add titanium white for value changes and one earth color for faster natural browns and skin-tone adjustments.
| Role | What to look for | Why it matters in a chart |
|---|---|---|
| Warm red | Leans orange | Makes stronger oranges and muted violets. |
| Cool red | Leans violet | Makes cleaner purples and more flexible rose mixtures. |
| Warm yellow | Leans orange | Makes warmer greens, golds, and sunlight mixtures. |
| Cool yellow | Leans green | Makes brighter spring greens. |
| Warm blue | Leans violet | Makes deeper violets and quieter greens. |
| Cool blue | Leans green | Makes cleaner greens and turquoise shifts. |
| Titanium white | Strong opaque white | Shows tinting strength and value loss clearly. |
| Earth color | Burnt sienna, umber, ochre family | Speeds up natural neutrals and prevents candy-colored mixes. |
Which Paul Rubens oil paint set fits this job?
If your goal is learning color, the set size should match how often you paint and how large you work. I would not automatically pick the biggest color count.
Best for first charts: 24 colors, 20ml
The Paul Rubens Professional Oil Paint Set 24 Colors 20ml is the easiest place to start if you want enough hue range without committing large tubes to practice grids. It is better for controlled learning than for repeated large canvases.
Best if you paint often: 20 colors, 50ml plus extra white
The 20-color 50ml set with extra Titanium White is more sensible if you are building tint charts. White disappears fast when you test values, skies, skin tones, and pastel mixtures.
The Oil Paint Color Mixing Chart You Actually Need
A useful chart has four layers: hue pairs, ratio steps, white tints, and neutral checks. Do not make one giant chart first. Make small charts that answer one question at a time.
Chart 1: primary-to-secondary mixes
Make three rows: red plus yellow, yellow plus blue, and blue plus red. For each row, paint five swatches: 4:1, 3:2, 1:1, 2:3, and 1:4. Label the tubes used. This gives you a real map of orange, green, and violet behavior.
Chart 2: white tint strength
Take each key mixture and add white in three stages. This is where many painters learn a painful truth: white does not just make color lighter. It also cools, dulls, and opacifies the mixture. A brilliant orange can become peach faster than expected.
Chart 3: complement neutral checks
Mix a color with a tiny amount of its complement. Red with green. Blue with orange. Yellow with violet. You are not trying to make brown immediately. You are learning how little complement it takes to reduce chroma.
Warm And Cool Primaries: The Shortcut To Cleaner Color
Warm and cool primaries matter because every tube has a bias. A blue that leans green mixes very differently from a blue that leans violet. When a red-biased blue meets a green-biased yellow, the hidden red cancels part of the green and the result looks duller.
This is why one “primary red, primary yellow, primary blue” palette can disappoint. It may technically cover the color wheel, but it will not always give you high-chroma secondaries.
| Goal | Choose | Avoid | Reason |
|---|---|---|---|
| Clean orange | Warm red + warm yellow | Cool red + cool yellow | Violet/green bias lowers chroma. |
| Clean green | Cool yellow + cool blue | Warm red-leaning blue | Red bias quietly neutralizes green. |
| Clean violet | Cool red + warm blue | Warm yellow-leaning red | Yellow bias muddies violet. |
| Natural gray | Complement pairs | Black plus white only | Complement grays feel more alive in paintings. |

How To Paint The Chart Without Wasting Half Your Tubes
Oil paint charts can waste a surprising amount of paint. The trick is to make small swatches, use a consistent knife or brush load, and separate learning charts from display charts. Your first chart should be a working document, not a poster.
- Cut your surface into small zones. Use rows no taller than a thumbnail. You need evidence, not decoration.
- Squeeze paint in tiny amounts. Start with half-pea quantities. Add more only if you run out mid-row.
- Mix with a palette knife when possible. Brushes hold old color near the ferrule and can contaminate subtle mixes.
- Use one brush for laying swatches. Wipe thoroughly between steps. Do not rinse in solvent after every square unless you want unpredictable oily residue.
- Write tube names immediately. A chart without labels becomes a color puzzle with no answer key.
- Let it dry before judging value. Some oil colors shift as they set. Judge the wet chart for mixing behavior and the dry chart for painting decisions.
Tool note: do not use a fan brush for the chart
The Paul Rubens Professional Fan Brush has its place for texture, foliage, and broken edges, but it is not my pick for chart swatches. Use a flat or filbert brush for consistent rectangles; save the fan brush for testing painterly effects after you understand the mixtures.
Do Not Let White Ruin Your Color Chart
Titanium white is necessary, but it is also bossy. It has high covering power, so it can turn transparent or high-chroma mixtures into chalky pastel versions quickly. Your chart should show white as a separate test, not as a default ingredient in every mix.
For each main color pair, make one row without white and one row with staged tints. This teaches two different skills: hue mixing and value control.
“If every color looks better only after adding white, the palette may be too dark for the subject, or the painter may be solving value before solving hue.”
This is especially important for skies, florals, portraits, and any painting with delicate transitions. Too much white gives coverage, but it can remove the luminous middle chroma that makes oil paint feel alive.
Best for repeated studio charts: 20 colors, 60ml
The Paul Rubens Oil Paint Set 20 Colors 60ml makes sense when you are painting larger practice panels or building multiple charts for landscapes, portraits, and florals. It is not necessary for the first chart, but the tube size matters once you repeat studies.
Special Colors: Useful, But Not Your Foundation
Metallic, glitter, neon, and specialty oil colors are expressive finishing colors. They should not be the backbone of a color mixing chart. Their reflective particles or fluorescent character can make a chart look exciting while teaching very little about ordinary hue relationships.
Use for highlights, decorative work, and selective accents. Keep them out of your base skin, sky, and landscape charts.
Use when the subject needs artificial intensity: signage, stylized florals, pop art, or social-media-forward color.
Use heavily in realistic charts. They are less dramatic but far more helpful for portraits, shadows, and natural objects.
Buy later: metallic glitter oil paint
The Paul Rubens Metallic Glitter Oil Paint Set 9 Colors 60ml is interesting for accent work, but I would not use it to learn basic color mixing. Treat it like a specialty layer.
Also buy later: neon oil color
The Paul Rubens 12 Neon Colors Oil Paint Set belongs in a special-effects palette. It is not the right first purchase for naturalistic mixing, portrait color, or restrained landscape work.
Surface Matters: Make Your Chart On Something Similar To Your Painting Surface
Paint behavior changes with surface absorbency and texture. A chart on slick paper may not predict what happens on canvas. A chart on rough absorbent paper may make paint look drier and less saturated than it does on a primed panel.
If you are making charts for oil painting, use canvas paper, primed canvas, or acrylic/oil-friendly paper. Watercolor paper can work for dry reference swatches if it is properly prepared, but it is not automatically an oil painting surface.
Surface caveat: watercolor paper is not a default oil surface
The Paul Rubens Cold Press Watercolor Paper 40 Sheets 100 Cotton is useful across wet media, and the texture can be handy for reference swatches. But for oil paint, use a suitable barrier or choose an oil-ready surface. Do not put oil paint directly onto unprepared paper and expect archival behavior.
For paper-specific decisions, the guides on hot press vs cold press watercolor paper and watercolor blocks vs pads are useful, even if your final oil chart should live on an oil-appropriate support.
Three Practical Charts For Real Painting Problems
Once the basic chart is done, make smaller charts by subject. These are more useful than a single massive color wheel because they match the decisions you make while painting.
1. Landscape green chart
Mix three greens from different yellow-blue pairs. Then mute each with a tiny amount of red or burnt sienna. Label which mixture feels like spring grass, distant trees, olive shadow, and warm reflected light.
2. Portrait neutral chart
Start with an orange family mixture, then cool it with a blue touch and lighten with white. Add earth color in tiny increments. The point is not to make one “skin tone.” It is to learn how quickly flesh mixtures become gray, chalky, or too orange.
3. Floral high-chroma chart
Test red-violet, pink, orange, and yellow mixtures before adding white. Many floral colors lose life when over-tinted. A useful floral chart shows where saturation peaks before the mixture becomes pastel.
My Recommended Buying Logic For This Specific Topic
If the only question is “what should I buy for oil color mixing charts,” here is the clean version.
| Painter situation | Buy | Skip for now | Why |
|---|---|---|---|
| First oil chart, small budget | 24 colors, 20ml | Neon, metallic, very large tubes | Enough colors to learn bias without overbuying. |
| Regular practice and repeated tint charts | 20 colors, 50ml with extra white | Small white tube only | White is the first tube most chart-makers punish. |
| Larger canvases and studio drills | 20 colors, 60ml | Too many tiny tubes | Large tubes are less precious when you need repeated mixtures. |
| Decorative accents and stylized effects | Metallic 9 colors or Neon 12 colors | Using them as base primaries | They are effect colors, not foundation colors. |
Common Oil Paint Mixing Mistakes
Most bad mixes come from impatience, not lack of talent. Here are the mistakes I would fix first.
Mix the hue first. Then test value. White can hide whether the original mixture was correct.
Black can be useful, but complement-based darks often sit better inside colorful paintings.
Old color in the brush can shift a mixture enough to make your chart misleading.
Judge both wet and dry swatches. A chart is a reference only after it has settled.
If you are still deciding whether oil paint is the right medium, compare this process with the faster setup described in oil painting for beginners. Oil rewards patience; if you want immediate layering and faster cleanup, acrylic may be less frustrating.
FAQ
What colors do I need for an oil paint color mixing chart?
Use warm and cool versions of red, yellow, and blue, plus titanium white and one earth color. This limited palette teaches more than a large random set because you can see how color bias affects every secondary and neutral.
Should I use black in my oil color mixing chart?
You can include black as a separate test, but do not rely on it for every shadow or gray. Complementary mixtures often produce more natural darks and grays, especially in landscapes, portraits, and floral paintings.
Why do my oil paint mixes turn muddy?
Oil paint turns muddy when you accidentally mix complements, overwork too many pigments together, or use primary colors with hidden biases that cancel each other. A labeled chart helps you identify which pair is causing the dull shift.
Are metallic or neon oil paints good for mixing charts?
They are good for specialty effect charts, but not for your first foundational chart. Learn ordinary primaries and neutrals first. Then add metallic or neon colors as separate accent tests.
What is the best Paul Rubens oil paint set for color mixing?
For a first chart, the 24-color 20ml set is practical. For repeated practice, the 20-color 50ml set with extra titanium white is stronger because tint charts consume a lot of white. For larger studio work, the 20-color 60ml set gives more breathing room.
Bottom Line
Do not make an oil paint color mixing chart to prove you own a lot of colors. Make one to answer your next painting problem.
Start small. Label everything. Separate hue, value, and neutral tests. Keep specialty colors out of the foundation chart until you know what ordinary primaries can do.
That is the difference between a chart that looks nice for one afternoon and a chart that quietly saves every painting after it.
