Converting CMYK to RGB
CMYK is the subtractive, four-ink model used by printers, expressed as cyan, magenta, yellow, and key (black) percentages. RGB describes a color as amounts of red, green, and blue light from 0 to 255 — the native model of every screen and camera.
The key thing to understand converting between CMYK and RGB is that CMYK is a print (subtractive, ink-based) model while RGB is a screen (additive, light-based) model. The conversion is a close mathematical approximation — the two gamuts don't overlap perfectly, so a color that looks vivid on screen can print duller. For accurate print work, always confirm against your printer's ICC profile or a physical proof.
This CMYK to RGB converter works instantly in your browser: type or pick a CMYK color and the RGB value updates live, along with every other common format so you can copy whichever you need. Nothing is sent to a server, and it is completely free with no limits.
When do you need RGB?
Reach for RGB when you are working on digital screens, programming, and CSS rgb() values. Designers and developers routinely convert CMYK to RGB to move a color between a print workflow and a web one without eyeballing it. If you want to grab a color straight from an image instead of typing it, try our color picker from image, or build a full scheme with the palette generator.
You can also convert in the other direction with our RGB to CMYK converter, or jump to any other format — the tool always shows HEX, RGB, HSL, HSV, and CMYK side by side.
