Question 1

How do I convert HEX to CMYK?

Accepted Answer

To convert HEX to CMYK, first convert the HEX code to RGB, then transform RGB to CMYK. The Key (K) channel is calculated as 1 minus the maximum of R, G, B (normalized to 0-1). Cyan, Magenta, and Yellow are then derived relative to K.

Question 2

Why do CMYK values differ from what I see on screen?

Accepted Answer

CMYK is a subtractive color model used in printing, while screens use additive RGB. The conversion is an approximation — actual print output depends on ink, paper, and ICC color profiles. For critical print work, use professional color management software with proper ICC profiles.

Question 3

When should I use CMYK instead of HEX?

Accepted Answer

Use CMYK for print design (brochures, business cards, packaging) and HEX for digital/web design. CMYK values are essential when sending files to a commercial printer, as they represent the physical ink percentages used in four-color printing.
