What people use Color Wheel for

• Finding complementary, triadic or analogous colours for a scheme.
• Exploring hue relationships when building a palette.
• Choosing an accent colour that works with an existing primary.

Color Wheel: limits and things worth knowing

• Harmony rules are geometric relationships on the hue circle: complementary is 180° apart, triadic 120°, analogous adjacent, and split-complementary either side of the opposite.
• The traditional artists' wheel (RYB) and the digital wheel (RGB/HSL) place complements differently — red's opposite is green in RYB and cyan in RGB, which is why colour theory from painting does not transfer directly to screens.
• Equal hue spacing does not give equal perceptual spacing. Yellows occupy a much narrower perceptual band than blues, so a mathematically triadic scheme can look unbalanced.
• Harmony rules produce hue relationships only. Saturation and lightness still need adjusting, and contrast still needs checking.

Is it private and secure?

Your privacy is built in. Color Wheel runs completely on your device, so whatever you enter stays in your browser and is never transmitted, logged or stored on any server.

Network activity: none. Nothing is sent and nothing is fetched. This tool makes no network request at all once the page has loaded — which is why it keeps working if your connection drops.

You do not have to take that on trust — our privacy proof page publishes the Content-Security-Policy that enforces it, lists every third party it permits, and shows how to verify the whole claim yourself.
