What Each Format Means
- HEX — a 6-digit code (e.g. #3366CC) used almost everywhere in web design and CSS.
- RGB — Red, Green, Blue values from 0-255, matching how screens actually mix light.
- HSL — Hue, Saturation, Lightness — often more intuitive for adjusting a color’s shade.
- HSV — Hue, Saturation, Value (sometimes called HSB) — common in image editing software.
- CMYK — Cyan, Magenta, Yellow, Key (black) — used for print, not screens.
A Note on CMYK
CMYK values here are calculated mathematically from RGB using the standard conversion formula. Real-world printing uses device-specific color profiles that can shift results slightly — for print-critical work, always check a proof from your actual printer rather than relying on any on-screen CMYK calculation alone, including this one.
FAQ
Is my color data uploaded anywhere?
No. Every conversion is calculated locally in your browser using standard math formulas. Nothing is sent to our server.
Which field can I edit?
Any of them. Edit HEX, RGB, HSL, HSV, or CMYK directly, or use the color picker — all other fields and the preview swatch update automatically.
Why do the numbers change slightly if I convert back and forth?
Each format uses a different numeric scale, so converting between them involves rounding. A difference of 1 in the final digit after several round-trips is expected and not a sign of an error.
