Contemporary artists and designers often use a computer and monitor.
Computer screens use an RGB system. As a consequence, RGB has become an important way of thinking about and organising colour. The computer monitor is itself a 'medium', like paper or fabric, and the Web now has 216 'web safe' colours allocated to it.
Graphics software can also offer HSV and CIE L*a*b.
