See Why Colors Work Together
You’ve picked a warm orange for your brand. Now what? Just guessing at complementary colors leads to those “something feels off” palettes that look thrown together. Color harmony is geometric, it’s about angular relationships on the color wheel, and this tool makes those relationships visible.
Pick a base color and you’ll see all six major harmony types at once, each with an interactive color wheel showing exactly where the colors sit. Markers on the wheel make the geometry obvious. Click any color in any palette strip to copy its HEX code.
Six Harmonies from One Color
Start with that warm orange (#FF8C00). Here’s what you get:
Complementary: a deep blue directly opposite on the wheel. High contrast, high energy. Great for CTAs against a warm background.
Analogous: the reds and yellows neighboring your orange. Calm, unified feel. Works beautifully for warm-toned landing pages.
Triadic: your orange plus a green and a violet, equally spaced at 120°. Vibrant but balanced. Three entirely different palettes from the same starting point.
Split-Complementary: your orange plus the two colors flanking its complement. You get contrast without the full intensity of a direct complementary pair.
Tetradic and Square: four-color harmonies that give you the most variety. Harder to pull off, though, if you use all four at equal intensity, nothing stands out. Let one dominate and use the rest as accents.
The Emotional Difference
This is the part most people skip, but honestly, it’s what separates good palettes from great ones. Analogous palettes feel serene and professional. Complementary pairs feel bold and energetic. Triadic combinations feel creative and playful. The geometry isn’t arbitrary, our eyes perceive evenly-spaced color relationships as intentional, while random color choices feel chaotic.
Harmony Finder vs. Palette Generator
Both produce the same harmony colors. The difference is emphasis. This tool shows you the why: color wheel diagrams with position markers so you understand the geometric relationships. The Palette Generator is more about the what: quick palette output without the educational visualization.
You can mix harmony types in a single project, but do it carefully. A solid approach: use Analogous for your base palette and borrow one Complementary accent for elements that need to pop.
