Five essential parts

Unpacking the NCS System

Elementary Colours

Elementary Colours

Six elementary colours are perceived as “pure” and hold the key to the 10 million colours our eyes can detect. A pure yellow, for instance, does not include red or green, just as a pure blue contains no red or green.

These six colours form the foundation of the NCS notations, which make it possible to describe any of the 10 million colours that form our world.

NCS Colour Space

NCS Colour Space

Imagine colours in a three-dimensional (3D) space. White and black are on a vertical axis while the other four elementary colours are plotted in a circle around it. This allows colours to be identified with NCS Notations with greater accuracy than a 2D space would provide.

NCS Colour Circle

NCS Colour Circle

As one of the dimensions of the colour space, the NCS Colour Circle cuts horizontally through the centre. It describes the hue in relation to the four elementary colours.

 NCS Colour Triangle

NCS Colour Triangle

As the vertical dimension of the colour space, the NCS Colour Triangle defines each of the different hues' nuance.

NEUTRAL COLOURS: All pure grey nuances are considered neutral. They run along the back of the triangle and lack a hue. They are coded with N as neutral.

NCS Notation: NCS S 1040-R20B

NCS Notation

The colour notation or code NCS S 1040-R20B has the nuance 1040, i.e. 10% blackness and 40% chromaticness. The hue, R20B, is a red (R) with 20% blue (B) in it.
