Frequently Asked Questions

How does CMYK to HEX conversion work?
CMYK values are first converted to RGB by applying the formula R=255*(1-C)*(1-K), then the RGB values are converted to a hexadecimal color code.
Why do CMYK colors look different on screen?
CMYK is designed for print and uses subtractive color mixing, while screens use additive RGB. Some CMYK colors cannot be exactly represented in RGB, so slight differences are expected.
What CMYK values produce black?
C:0 M:0 Y:0 K:100 produces pure black (#000000). You can also get dark tones by combining high values of C, M, and Y with K.
