Too many colors. Too much saturation. Too much red where it had no business being. If you've ever delivered a project and felt something was visually "off" without being able to pinpoint it — welcome to the club. The good news: there's a method.
The Chijiwa method in 8 steps
Professor Hideaki Chijiwa of Musashino University of Fine Arts (Tokyo) formalized a structured approach for building durable, culturally coherent, and cross-media effective palettes.
1. Define the intent — Why this palette? For whom? Red in a health app says something entirely different from red on a festival poster. Color is never neutral.
2. Review the basics — Hue, saturation, brightness, contrast. Analyze palettes that work for similar projects before making any choices.
3. Choose the dominant color first — The primary color is the one covering the largest surfaces. It sets the overall tone. Accent colors come after — or are imposed by an existing brand identity, in which case you build the dominant around them.
4. Select the values — The lightness or darkness of a color impacts the overall impression just as much as the hue itself. Define the emotional register: bright and dynamic, or calm and dignified? Same hue family, different values: radically different effects, harmony preserved.
5. Check hue compatibility — Test the preliminary palette as a whole. If the contrast is too harsh or too flat, refine with intermediate hues: a red-orange may work where pure red clashes.
6. Limit the number of colors — Two or three is usually enough. Four requires care. Five is often too many. Beginners systematically use too many vivid colors: it's the most common mistake, and the most visible one.
7. Test in real conditions — Apply the palette to genuine representative pieces. If the harmony holds, designs "settle" naturally. If not, back to step 5.
8. Keep a palette journal — Document palettes that work: project name, color chips, context, why it works. This notebook becomes an invaluable resource.
The main families of chromatic harmony
Analogous (adjacent hues): soft, restful, easy to create — but low contrast, low impact.
Complementary (two opposites): vibrant, memorable — hard to balance without aggression.
Split-complementary (one hue + the two adjacent to its opposite): more sophisticated than pure complementary, strong impact, better balance. Complex to master.
Triadic (three equidistant hues): contrasted but softer. Versatile.
Tetradic (two complementary pairs): the richest palettes — and by far the hardest to hold together.
Monochromatic (variations of a single hue): elegant, clean — often lacking punch.
The rule that actually matters
All these rules are starting points, not destinations. The best designers know how to apply them — and know exactly when to break them. Color is a tool. It works for you. Not the other way around.
