The conversions used
RGB is read directly from the HEX code's byte pairs. HSL is derived from RGB using the standard min/max channel formula that finds hue from which channel dominates, saturation from the spread between the lightest and darkest channel, and lightness from their average. CMYK is derived from RGB using the standard subtractive-color conversion, treating black (K) as whichever channel is darkest.
FAQ
Why is CMYK slightly different from what I see on screen?
CMYK is a print color model, converted here using a standard mathematical formula from RGB — but real printers and inks vary, so a CMYK value calculated this way is a close approximation, not an exact match to what a specific printer will produce.
What does HSL stand for?
Hue, Saturation, and Lightness — a color model that's often more intuitive to reason about than RGB, since you can adjust just the lightness or saturation of a color without recalculating all three RGB channels.
Can I type a color code instead of using the picker?
Yes — type or paste a 6-digit HEX code into the text field, and the picker swatch and all other formats update to match.
Is my color choice sent anywhere?
No. Every conversion happens instantly in your browser — nothing is sent to Online Tool Store or any other server.
