This color harmony generator is an all-in-one tool that calculates complementary, analogous, triadic, split-complementary, and tetradic schemes simultaneously from a single base color, so you can compare every classic color theory relationship at once instead of running separate tools. It's ideal for designers exploring which harmony type best fits a project, students studying color theory who want to see all the rules applied to the same color side by side, and developers building a palette picker feature. Enter one base color and instantly see every scheme type rendered with swatches and HEX/RGB/HSL values, making it easy to switch between harmony types without re-entering your starting color. Every calculation happens locally in your browser, so your base color and the resulting schemes are never uploaded or logged anywhere. Each harmony type uses the exact standard hue-wheel angles defined by color theory - 180° for complementary, 120° steps for triadic, and so on - so results are always mathematically correct. Enter your base color below to see every harmony type generated at once.

Frequently asked questions
What color harmonies does this tool generate?
It generates complementary, analogous, triadic, split-complementary, and tetradic schemes all from the same base color.
What is split-complementary?
Split-complementary uses a base color plus the two hues adjacent to its direct complement, giving strong contrast with a bit less visual tension than pure complementary.
Which harmony type should I use for my project?
It depends on the mood you want - complementary and triadic give bold contrast, analogous and monochromatic feel calmer, and tetradic offers the most variety for complex designs.
Can I compare multiple harmony types for the same color?
Yes, that's the main advantage of this tool - all schemes are generated from one base color simultaneously so you can compare them directly.
Does this replace the individual harmony generator tools?
It covers the same calculations in one place; the individual tools remain useful if you want a focused, single-scheme workflow.
Is color harmony theory based on strict math?
Yes, each harmony type corresponds to specific, fixed angular relationships on the 360-degree hue wheel, which this tool applies precisely.
