A color mixing chart turns guesswork into repeatable results for artists, designers, teachers, and makers.
This guide explains how to make a color mixing chart that is organized, accurate, and useful across different materials.
What a Color Mixing Chart Does
A color mixing chart maps how one color changes when combined with another.
It helps you predict secondary and tertiary colors, compare pigment behavior, and record formulas for future use.
In paint, dye, ink, and digital workflows, a chart becomes a reference tool that saves time and reduces waste.
The value of a chart is not only visual.
It also documents relationships such as saturation, tint, shade, opacity, undertone, and temperature.
Those details are especially helpful when matching colors for illustration, interior design, textiles, and brand work.
Materials You Need
The exact materials depend on whether you are working with watercolor, acrylic, gouache, oil, dye, or digital color.
For a physical chart, keep the setup consistent so each swatch is easy to compare.
- Paper or card stock with enough weight for your medium
- A ruler or straightedge
- Pencil and eraser
- Watercolor, acrylic, gouache, or other chosen pigments
- Brushes, palette knife, or applicators
- Water, mixing palette, and cloth or paper towels
- Labels, fine-tip marker, or archival pen
- Optional: white and black paint for tints and shades
For digital charts, use a design program such as Adobe Illustrator, Photoshop, Procreate, or Affinity.
Create a grid, define swatch areas, and keep color mode in mind if you plan to print the chart later.
How to Make a Color Mixing Chart Step by Step
1. Choose your base colors
Start with a limited palette.
For traditional color theory, three primaries are common, but many artists prefer a practical set such as warm and cool versions of red, yellow, and blue.
A limited palette makes the chart easier to read and more reliable.
Common choices include cadmium red, alizarin crimson, ultramarine blue, phthalo blue, cadmium yellow, and hansa yellow.
If you want more nuanced results, include a neutral white and a deep black or payne’s gray.
2. Draw a grid
Create a square or rectangular grid with equal-sized cells.
A simple matrix works well: place one color set across the top and the same set down the left side.
Each intersection will show the result of mixing those two colors.
Leave enough space for labels and notes.
If the squares are too small, subtle differences in hue and value become hard to see.
A larger grid is better for precision, especially when you are building a chart you will reuse often.
3. Label the axes clearly
Write the color names or pigment codes along the top and side of the grid.
If you use professional paints, include pigment identifiers such as PB29 or PR122, because the pigment code is often more dependable than a marketing color name.
Labeling matters because different brands may use the same name for slightly different formulas.
Clear labels make your chart a better reference for future projects and help you repeat results consistently.
4. Fill the pure color swatches
Before mixing, paint the base colors in their corresponding row and column.
This gives you a visual anchor and makes the chart easier to scan.
Apply each swatch with consistent coverage so the paint film is even and comparable.
If you are making a chart with transparent pigments like watercolor, use a consistent water ratio.
If you are working with opaque paints like gouache or acrylic, keep the paint thickness similar from swatch to swatch.
5. Mix each color combination
Combine the colors at a controlled ratio, such as 1:1, and apply the mixture to the matching grid cell.
Clean your brush or mixing tool between colors to avoid contamination.
Record the exact ratio if you want the chart to support repeatable formulas.
To make the chart more useful, you can add several ratio columns for each pairing, such as 3:1, 1:1, and 1:3.
This helps you see how the blend shifts as one color dominates.
6. Add tints and shades
Mix each color with white to create tints and with black or a dark neutral to create shades.
This extends your chart beyond simple hue mixing and shows how each pigment behaves across value ranges.
Some pigments become chalky when lightened, while others stay bright and clean.
Darkening can also shift a hue unexpectedly, especially with modern synthetic pigments or transparent dyes.
Recording those shifts makes your chart more practical.
How to Organize the Chart for Clarity
A good color mixing chart is easy to scan.
Use consistent spacing, clean edges, and a logical order.
Place warm colors near warm colors and cool colors near cool colors if you want to highlight temperature differences.
- Group primaries together
- Keep labels aligned and legible
- Use the same brush size for each swatch
- Leave room for notes about opacity, drying shift, or staining
- Include a date and brand name if pigments may vary over time
If you plan to teach with the chart, consider adding a simple legend that explains terms like complementary colors, analogous colors, and neutralization.
That makes the chart useful for beginners as well as experienced users.
What to Watch for When Mixing Colors
Color mixing is affected by pigment bias, transparency, and medium type.
A clean primary on paper may look different when mixed with a second pigment that has a strong undertone.
For example, a red with a blue bias will create different results than a red with a yellow bias.
Drying shift is another important factor.
Watercolor and acrylic often dry darker or more muted than they appear wet.
If accuracy matters, let every swatch dry fully before comparing it to others.
Also note that some pigments are granulating, staining, or weak in tint strength.
These characteristics can change the appearance of your chart even when the proportions are identical.
How to Make a Color Mixing Chart for Different Mediums
For paint
Use a sturdy surface and consistent application.
Acrylic and gouache are good choices for chart-making because they dry relatively quickly and show distinct swatches.
Oil paint works too, but it requires more drying time and careful storage.
For watercolor
Use heavy watercolor paper and keep water levels consistent.
Because watercolor is transparent, the paper white influences every mixture.
That makes the chart especially useful for tracking transparency and layering behavior.
For dye or textile work
Create test strips or fabric swatches instead of paper cells.
Label fabric type, dye bath concentration, and timing, because absorbency and fiber content strongly affect the final color.
For digital color
Use a grid in RGB, CMYK, or Lab color mode depending on your workflow.
Digital charts are useful for web design, prepress, and brand systems, but printed output may differ from what you see on screen.
Calibrated monitors improve accuracy.
How to Keep Your Chart Accurate Over Time
Store the chart away from direct sunlight to prevent fading.
If you use physical pigments, note the brand, pigment code, paper type, and date made.
These details matter when you recreate the chart months later.
Update the chart when you change materials or notice new behavior in a pigment line.
A living reference is more useful than a one-time sample sheet.
Many professionals keep separate charts for opaque paints, transparent paints, and special-effect colors so the data stays clean and easy to compare.
For best results, make a second chart using your most-used palette.
That smaller reference sheet is often the one artists reach for during daily work because it reflects the colors they actually mix most often.
