How it works
1
Choose a color
Use the color picker for visual selection, or type directly into any of the HEX, RGB, HSL or CMYK fields.
2
All formats update instantly
Editing any field recalculates and syncs all other formats in real time. The large swatch reflects the current color.
3
Check accessibility
Contrast ratios against white and black are computed using the WCAG 2.1 relative luminance formula. Badges indicate whether the color passes AA (4.5:1) or AAA (7:1) thresholds.
