Rgb

The Rgb color space consists of all possible colors that can be made by the combination of red, green, and blue light. It's a popular model in photography, television, and computer graphics.

Cmyk

Cmyk is similar to the Cmy color space, with the addition of black (k). In theory the black component is not necessary, however this color space is primarily used in color printing where the mixture of cyan, magenta, and yellow result in a brown color rather than black.

We'll be adding support for ICC profiles to this page soon, but it's already available on our color converter page.
