Tetradic Color Scheme
A tetradic color scheme uses four hues arranged as two complementary pairs, forming a rectangle on the color wheel. It is the richest and most vibrant of all the schemes — and the hardest to balance — so it rewards a careful hand and a single colour in the lead.
A tetradic color scheme (also called double-complementary or rectangular) uses four colors set as two complementary pairs that make a rectangle on the wheel. It is vivid and full of contrast, so you let one hue dominate and treat the other three as accents. Build one below in real paint.
Drag the base dot around the wheel — the scheme follows the rule. Each color snaps to the nearest real paint. Tap a swatch to copy its hex.
This is the tetradic scheme drawn on the wheel — drag the base dot to explore, then open any result as an editable palette in real paint.
Pick two complementary pairs — for example a blue-orange pair and a yellow-violet pair — and they will sit as a rectangle on the wheel. Because all four hues are strong, choose one to cover most of the room, then use the other three in smaller doses on trim, decor and accents. Balance warm against cool so the palette feels intentional rather than busy, and lean on neutrals or muted tints to let the four colors breathe.

Our color tools run on our own catalogue of 26,000+ real paint colors across 16 brands — Benjamin Moore, Sherwin-Williams, Behr, Dulux, RAL and more — with the color math (HSL and CIELAB matching) computed in-house, not scraped from summaries. Every color you pick maps to a real, buyable paint with its code, so what you see here you can actually take to the store. We review and update these tools and their data regularly.

What is a tetradic color scheme?+
A scheme built from four colors arranged as two complementary pairs, which form a rectangle on the color wheel. It is the most vibrant and varied scheme, ideal for eclectic, characterful rooms when used sparingly.
What is the difference between tetradic and square color schemes?+
Both use four colors, but a square scheme spaces them evenly at 90 degrees apart, while a tetradic (rectangular) scheme groups them as two complementary pairs sitting closer together. Tetradic gives you a clear warm-cool split and is a little easier to weight toward one dominant hue.
How do I keep a tetradic scheme from looking chaotic?+
Let one color dominate and keep the other three as supporting accents rather than splitting the room evenly. Balance warm and cool, soften or mute at least one pair, and lean on neutrals so the four hues read as composed instead of competing.
Are these real paint colors?+
Yes — every color in the scheme is matched to real, buyable paint across 16 brands, with the exact names and codes so you can take the palette straight to the store.
