Quick answer
Complementary colors sit opposite each other on the color wheel. On the painter's (RYB) wheel the pairs are red–green, blue–orange and yellow–violet. Placed side by side, complements make each other look brighter. Mixed together, they cancel toward grey or brown, which is why painters use them for shadows and natural neutrals.

What makes two colors complementary
Two colors are complementary when, together, they contain the whole range of the color circle, so neither has anything the other lacks. On a color wheel they sit directly opposite each other.
The traditional painter's wheel, built on red, yellow and blue primaries, gives three famous pairs: red ↔ green, blue ↔ orange and yellow ↔ violet. Each pair is a primary plus the secondary mixed from the other two primaries. Green, for example, is made from yellow and blue, which is everything red isn't.
Complements behave in two ways that look opposite but come from the same fact:
- Next to each other, they intensify each other. Your eye heightens the difference, so the red looks redder beside green. This is simultaneous contrast.
- Mixed together, they neutralize each other into browns and greys, because together they absorb most of the light.

Open full mixer →Painter's wheel vs. digital wheel
If you've used a digital color tool, you may have seen different pairs: red ↔ cyan, green ↔ magenta, blue ↔ yellow. That's because screens mix light (additive RGB), and their complements are defined so that together they make white light. Paint mixes pigments, which subtract light. Printing inks use cyan, magenta and yellow, which sit closer to the modern optical opposites.
Neither wheel is "wrong." They answer different questions. For mixing physical paint, the most useful definition is practical: two paints are complements if mixing them gives a near-neutral grey. With real pigments, that means pairs like these:
- Ultramarine blue ↔ burnt sienna or cadmium orange
- Phthalo green ↔ alizarin crimson or a quinacridone red
- Dioxazine purple ↔ a lemon or Hansa yellow
- Cadmium red light ↔ a blue-green such as phthalo green or viridian
The chromatic circle on the Mixer page uses a painter's wheel, so the opposites it shows are the ones that behave like complements in paint.
Complementary color chart
Painter's (RYB) complements for common colors, and what you get when you mix them.
| Pair | Mixed together |
|---|---|
| Red ↔ green | Brown to deep neutral |
| Blue ↔ orange | Brown or slate grey |
| Yellow ↔ violet | Olive-brown to grey |
| Purple ↔ yellow ochre (+ white) | Soft mauve-grey |
| Pink ↔ soft green (+ white) | Soft sage-grey |
| Brown ↔ blue | Near-black or dark grey |
| Teal ↔ coral (+ white) | Warm grey |
How painters use complements
For contrast and focus
Place a small accent of a color's complement where you want the eye to land: an orange boat on a blue sea, a red poppy in a green field. Keep one color dominant and use the other sparingly. Equal amounts of two saturated complements can feel loud and unresolved.
For neutral and muted colors
A touch of the complement is the most natural way to tone down a color that's too intense. A green that looks artificial straight from the tube calms down with a hint of red. Mixed in larger amounts, complements give harmonious browns, greys and shadows without black.
For vibrating greys
Greys mixed from complements and then lightened with white feel more alive than black-and-white greys. Leaning them slightly toward one side or the other gives warm and cool greys that sit beautifully next to pure color.
Finding the complement of any paint
You don't need to memorize a chart. Two practical methods work for any tube on your palette:
- The neutral test. Mix your paint with a candidate complement in small steps. If you can reach a convincing grey (neither warm nor cool) somewhere along the way, the pair works as complements. If the mix always leans one way, try a neighbor on the wheel, for example a more orange red, or a bluer green.
- The afterimage test. Stare at a saturated swatch for about 20–30 seconds, then look at a white sheet. The faint afterimage you see is roughly its visual complement. It's a lovely demonstration of how your eyes adapt, though it won't always match the best pigment partner exactly.
Afterimages and simultaneous contrast also explain why a grey placed on a red background can look slightly greenish. Your eye tints neutrals toward the complement of their surroundings, so judge mixtures in context.
Related harmonies
Complements are the base of several other color schemes. A split-complementary scheme uses one color plus the two neighbors of its complement, for example blue with yellow-orange and red-orange. It has strong contrast with less tension.
A triadic scheme uses three colors evenly spaced around the wheel. Analogous schemes use neighbors on the wheel and feel calm, and a single complementary accent can bring them to life. You can explore all of these in the chromatic circle.
Recipes by medium
Proportions are starting points in parts by volume. Pigment strength varies by brand, so add strong colors gradually. The swatches are computed with Pigmento's pigment-mixing model and are approximations.
Warm grey
1 Ultramarine Blue + 2 Cadmium Orange + 4 Titanium White (parts). Lean toward orange for warm grey, toward blue for cool grey.
Muted green
4 Sap Green + 1 Cadmium Red Light (parts). A little red takes the 'plastic' edge off any green.
Neutral dark
1 Phthalo Green (BS) + 1 Alizarin Crimson (parts). A near-black made from complements.
Silvery grey
1 Ultramarine Blue + 1 Burnt Sienna + 6 Titanium White (parts). A favorite for skies, stone and atmospheric distance.
Muted violet
1 Dioxazine Purple + 1 Yellow Ochre + 3 Titanium White (parts). Yellow ochre calms purple into a soft, smoky violet.
Toned-down orange
4 Cadmium Orange + 1 Ultramarine Blue (parts). A terracotta that sits comfortably in a landscape.
Transparent grey
1 Ultramarine Blue + 1 Burnt Sienna (parts). Dilute for clouds and cast shadows. It granulates beautifully.
Soft neutral
1 Alizarin Crimson + 1 Sap Green (parts). A transparent neutral that glazes cleanly.
Muted yellow
5 Lemon Yellow + 1 Dioxazine Purple (parts). For shaded yellow objects like lemons, straw and fabric.

Frequently asked questions
What are the three complementary color pairs?
On the traditional painter's (RYB) wheel the pairs are red and green, blue and orange, and yellow and violet (purple).
What is the complementary color of blue?
On the painter's wheel, orange. In paint, ultramarine blue is commonly paired with burnt sienna or cadmium orange to make neutrals. On a digital RGB wheel the opposite of blue is yellow.
What happens when you mix complementary colors?
They neutralize each other. Small amounts lower the saturation of a color. Roughly balanced amounts make a brown, grey or near-black depending on the pigments.
Why do complementary colors look good together?
Placed side by side they increase each other's apparent intensity through simultaneous contrast, which creates energy and focus. Most painters let one dominate and use the other as an accent.
What is the complementary color of yellow?
On the painter's color wheel it's violet (purple). Mixing a little violet into yellow darkens and dulls it into a natural shadow color, and placing violet next to yellow makes the yellow look brighter. On an RGB screen wheel, yellow's complement is blue instead.
What is the complementary color of purple?
Yellow. A blue-violet pairs best with a warm yellow-orange, and a red-violet pairs best with a yellow-green. To mute a purple, add a little yellow ochre, which is gentler than a bright yellow.
