Question

Difference between Cymk & RGB?

Answer 1

If you have a basic color ink jet printer, you have probably used CMYK, which stands for Cyan (blue), Magenta (red), Yellow, and Key (black).  CMYK is called subtractive because inks “subtract” brightness from white paper, which is the primary background.  Black is produced by combining CMY, which is how you can print black on an ink jet printer if you only have a single blue, yellow, and red ink cartridge.

RGB, which stands for Red, Green, and Blue, is an additive color model which is used to describe a light or video process.  White is produced by combining the maximum intensities of R, G and B light.
