Adjust a base color and compare practical harmony palettes locally before continuing to contrast, scale, or export tools.
Use the wheel for palette relationships rather than format conversion. Pick a base hue plus saturation/lightness and generate complementary, analogous, triadic or tetradic hue relationships with reusable HSL and HEX values.
| Role | Hue | HSL | HEX |
|---|
Harmony relationships are geometric hue suggestions. Contrast and accessibility still depend on lightness, foreground/background pairing and actual UI context.
HEX/RGB/HSL/HSV/OKLCH conversions are numerical color-model operations. CMYK output is an RGB-derived approximation rather than ICC-profiled print proofing. WCAG contrast ratios measure luminance contrast only and do not certify a full interface. Color-blindness previews are design simulations, not medical tests.
