About this tool

Color harmony from a base color

Color Wheel Tool turns a single base color into related harmony options such as complementary, analogous, triadic, and split-complementary schemes.

Use harmony as a starting point

Color-wheel relationships help narrow choices, but the final palette still needs contrast checks, saturation tuning, and role assignment for real UI use.

Design review clarity

Using harmony names makes color feedback easier. Instead of arguing over taste alone, teams can discuss whether the design needs contrast, cohesion, warmth, or a stronger accent.

Example usage

Input

#2563EB

Output

Complementary orange, nearby analogous blues, and triadic accent candidates.

FAQ

What are complementary colors?

Complementary colors sit opposite each other on the color wheel and create high contrast when used together.

What are analogous colors?

Analogous colors sit near each other on the wheel and usually create a calmer, more cohesive palette.

What is a triadic color scheme?

A triadic scheme uses three colors spaced evenly around the wheel, giving balance and variety when one color remains dominant.

Can color-wheel results go straight into UI?

Use them as a start, then check contrast, roles, dark mode, and color blindness behavior before shipping.
