NCS color system

The NCS color system (standing for "Natural Color System") is a color system designed by the Scandinavian Colour Institute. (Yes, they spell "color" differently in the name of the standard and the English translation of their name).

It is based on six "elementary colors": white, black, yellow, red, blue, and green. Colors are defined by three values, specifying the amount of "blackness", "chromaticity", and a percentage value between two of the colours yellow, red, blue or green. NCS color notations can also be tagged with a letter giving the version of the NCS color standard that was used to specify the color.

Examples of NCS color notation -- the colors of the Swedish flag:

• Yellow - NCS 0580-Y10R
• Blue - NCS 4055-R95B
