Frequently Asked Questions
Which color formats are supported?
Convert between HEX, RGB, HSL, HSV, CMYK, HWB, LCH, OKLCH, LAB, XYZ, and CSS named colors. Enter a value in any format and all others update in real time.
What is OKLCH?
OKLCH is a perceptually uniform color space - equal numerical changes produce equal perceived color shifts. It is becoming the preferred format for modern CSS color palettes because it produces predictable lightness and saturation adjustments.
HEX vs RGB - when to use which?
HEX (#FF5733) is compact and standard in CSS, design tools, and documentation. RGB (rgb(255, 87, 51)) is intuitive when you need to adjust individual channels or apply alpha transparency (rgba). Both represent the same color.
Why do CMYK values differ from screen colors?
CMYK is a subtractive color model for print (Cyan, Magenta, Yellow, Key/black). Screens use additive RGB. Not all screen colors can be accurately printed, and CMYK conversion is approximate. Use CMYK values as a starting point and calibrate with a printed proof.
