What is an NCS colour code?

The Natural Color System (NCS) is a scientific colour system that describes colours as the human eye perceives them. Each colour is assigned a unique NCS code.

What does an NCS code look like?

A standard NCS colour code consists of several components, for example:

S 2050-Y90R

(Standard, Nuance, Hue)

Structure of the code:

  • S= Standard (second edition, 2050 colours)
  • 20= Blackness
  • 50= Chromaticness (saturation)
  • Y90R= Hue (90% yellow, 10% red)

The six elementary colours

NCS is based on six elementary colours that everyone recognises:

White (W)

Black (S)

Yellow (Y)

Red (R)

Blue (B)

Green (G)

Why use NCS?

NCS is independent of material or medium. The same code works for paint, textiles, plastic, digital and print.

✓ Standardised

A global standard used by designers, architects and industry.

✓ Intuitive

Based on natural colour perception, not on technical RGB or CMYK values.
