This project produces a chart of small painted squares showing what happens when you mix red, yellow, and blue acrylic in different ratios, then lighten each result with white. You end up with about 40 labeled swatches and a clear sense of how far each tube can take you.
Color mixing feels like guessing until you see the ratios written beside the results. A chart turns that guesswork into a lookup table, so matching a wall color, a canvas shade, or a craft project gets faster.

Materials
- 1 sheet of heavy mixed-media paper or primed canvas paper, about 11 x 14 inches
- 3 tubes of acrylic paint: red, yellow, and blue
- 1 tube of white acrylic
- 1 palette knife or old plastic spoon for measuring
- 1 small flat brush, about 1/2 inch wide
- 1 ruler and 1 pencil
- 1 muffin tin or paper plate for mixing
- 1 jar of water and paper towels
Steps
Rule the grid
Pencil a grid of 1-inch squares, leaving a half-inch margin for labels. Aim for six columns and eight rows. Press lightly so lines do not show through the paint.
Set up a unit of measure
Decide that one scoop is one palette-knife tip of paint. Using the same scoop for every color keeps your ratios honest.
Paint the pure colors
Fill the first row with red, yellow, blue, and white straight from the tube. These are your anchors for comparison.
Mix pairs in three ratios
For each pair, such as red and yellow, mix 1:1, 2:1, and 1:2 scoops in a muffin cup. Paint a square for each and label it with the ratio in pencil.
Try the three-color mixes
Combine equal scoops of all three primaries to see a neutral brown or gray. Then tilt the ratio toward one primary to find warm and cool browns.
Add white to each mix
Beside every mixed square, paint a lighter square made by adding one scoop of white to it. Seeing the pairs side by side shows how white shifts both value and saturation.
Let it dry flat
Acrylic usually dries to the touch in 15 to 30 minutes, but darkens slightly as it cures. Wait a full hour before judging the final colors.
Label and display
Ink the ratios beside each square once the paint is dry.
Why these colors work
Red, yellow, and blue sit 120 degrees apart on a traditional wheel, so mixing two primaries lands you on the secondary between them, and adding the third pulls the mix toward a neutral. That is why equal parts of all three give a muted brown rather than a bright hue: the mix contains a color and its complement at once.
Editorial suggestion: When a mix looks dull, find the square it resembles and adjust by a single scoop.
Mistakes to avoid
Inconsistent scoop sizes
A heaping scoop of blue and a flat scoop of yellow are not a 1:1 mix. Level every scoop against the edge of the cup.
Judging wet paint
Acrylic dries darker, especially lighter tints. Compare swatches only after they have dried.
Mixing too little
Tiny puddles run out before you finish a square. Mix enough for the colored square plus a spare for adding white.
Forgetting to label as you go
A week later you will not remember which square was which. Write the ratio the moment you paint it.
Palette variations
- Swap in a cool trio of cyan (#00A3D9), magenta (#D6247D), and yellow (#FFE11A) for brighter violets and greens.
- Build an earth chart from burnt sienna (#8A3B1C), yellow ochre (#C9961A), and a dark teal (#1F4E55).
- Use black (#1A1A1A) as the lightness control instead of white and chart the resulting shades.
Safety
Acrylic is water-based, but keep it off skin when you can and never rinse large amounts down a sink; wipe brushes on a paper towel first. Keep food and drinks away from the mixing area.
