Frequently asked questions
Why do CMYK and RGB colors look different?
RGB is an additive model that mixes red, green and blue light for screens, while CMYK is subtractive and mixes cyan, magenta, yellow and black inks on paper. Screens can show some bright, saturated colors that ink simply cannot reproduce, so a vivid on-screen color may look more muted once converted to CMYK for print.
Will my printed colors exactly match what I see on screen?
Not always exactly. This converter gives an accurate mathematical conversion, but real print results also depend on your printer, paper and the ICC color profile your print shop uses. For critical work, treat the CMYK values as a strong starting point and confirm with a printed proof.
Is anything I enter sent to a server?
No. The conversion is calculated entirely in your browser, so the color values you type stay on your device and are never uploaded or stored.
