What is NCS?
NCS – Natural Colour System® is rooted in science, reflecting how we perceive colours. Using NCS Notations or codes, you can describe colour on any surface, whether it's fabric, paint or packaging.
What sets NCS apart?
It’s become the global go-to standard for defining and communicating colours, ensuring accurate and high-quality colour communication.
Why choose NCS?

Five essential parts
Unpacking the NCS System
Elementary Colours
The six elementary colours: white, black, yellow, red, blue and green are perceived as “pure” and hold the key to describing the 10 million colours we see. A pure yellow, for instance, is not perceived as reddish or greenish, just as a pure red is not perceived as yellowish or bluish.
These six elementary colours form the foundation of the NCS notations, making it possible to describe all of the 10 million colours that form our world.
NCS Colour Space
Colours can be described in a three-dimensional (3D) space, a colour space. White is on the top and black is on the bottom of the vertical axis, while the four chromatic elementary colours are arranged in a circle around it. This allows colours to be identified with NCS Notations exactly as we perceive them.
NCS Colour Circle
As one of the dimensions of the NCS Colour Space, the NCS Colour Circle cuts horisontally through the centre. It describes the hue of the colour in relation to the four chromatic elementary colours.
NCS Colour Triangle
In the vertical dimension of the NCS Colour Space, one NCS Colour Triangle is defined for each hue. A colour’s position within the triangle defines its nuance.
NEUTRAL COLOURS: white, black and all grey colours have no hue and are notated with -N for neutral. They are located along the vertical side of the NCS Colour Triangle.
NCS Notation
The NCS notation NCS S 1040-R20B has the nuance 1040, i.e. 10% blackness and 40% chromaticness. The hue R20B denotes a red (R) with 20% blue (B).
