Four synchronized formats
Move naturally between HEX, RGB, HSL, and CMYK without re-entering the same color or relying on rounded intermediate values.
Move between HEX, RGB, HSL, and CMYK, test accessible contrast, and turn one color into a useful palette.
Edit any color model on the right. Every other value and palette updates immediately.

Choose the format that fits your workflow. Every conversion is recalculated from the active color so the controls stay predictable and in sync.
Use the visual picker, type a HEX value, or edit individual RGB, HSL, or CMYK channels.
All color models stay synchronized, ready to copy into CSS, design software, documents, or brand guidelines.
Test foreground contrast, explore harmonious colors and shades, save swatches, or export the palette as CSS variables.
Move naturally between HEX, RGB, HSL, and CMYK without re-entering the same color or relying on rounded intermediate values.
Measure the exact contrast ratio and see AA and AAA results for normal and large text against a second color.
Explore complementary, analogous, and triadic colors, generate a shade scale, save swatches locally, and export CSS variables.
Enter a three- or six-character HEX color. The red, green, and blue channel values update immediately, along with HSL and CMYK.
RGB mixes emitted red, green, and blue light for screens. CMYK estimates cyan, magenta, yellow, and black ink percentages for print workflows. Actual printed results still depend on printer and color profile.
WCAG 2.2 Level AA requires at least 4.5:1 for normal text and 3:1 for large text. Level AAA uses 7:1 for normal text and 4.5:1 for large text.
Only swatches you explicitly save are stored in this browser. The active color and generated palette are calculated locally and are never uploaded.
Use them as a general conversion reference. Production printing requires an ICC color profile, substrate, ink, and press settings, which a browser-only mathematical conversion cannot model.
