Color converter for real UI work
Convert color values, check contrast, and explore related palettes before a design token lands in production.
A 4.5:1 contrast ratio is the usual WCAG baseline for normal body text. Large text has a lower threshold, but weak contrast still hurts real users.
Suggested color relationships
Color format guide
HEX
A compact format used widely in web design, typically written as a six-digit hexadecimal value.
RGB
A screen-oriented color model based on red, green, and blue light values.
HSL
A more human-readable model built around hue, saturation, and lightness. It is useful when creating lighter, darker, or related UI states.
CMYK
A print-oriented model based on cyan, magenta, yellow, and key black. Expect some drift when translating bright screen colors into print.
Contrast
Contrast affects forms, dashboards, pricing tables, error states, and every place a user has to read quickly.
Frequently asked questions
Why do RGB and CMYK conversions drift slightly?
Screen color and print color operate in different color spaces. Some RGB colors simply cannot be reproduced exactly in CMYK.
What does the WCAG contrast score mean?
It measures how readable foreground and background colors are together. Higher values generally mean stronger readability for text.
Should brand colors be used for body text?
No. A brand color that works well for logos or accents may fail as body text. Use stronger neutrals or adjusted shades when readability matters.
Why do colors look different between tools?
Different displays, color profiles, browsers, and print workflows can render the same numeric value differently. Treat conversion as a practical guide, then test in the target medium.
