Frequently Asked Questions
Which color formats does it convert between?
HEX, RGB, HSL, and CMYK are all shown simultaneously and update together as you adjust the color.
Is the CMYK conversion accurate for professional printing?
It uses a standard mathematical RGB-to-CMYK formula suitable for general reference - for critical print jobs, confirm against your printer's specific color profile.
Can I paste a color name like "tomato" instead of a hex code?
The input expects a HEX or picker-selected value; named CSS colors aren't parsed directly.
