The Colour Space

To accompany this innovative marker concept Letraset has devised its own unique, digitally structured colour system, comprising 300 colours. These colours have been specially selected to meet today's trends, reflecting the need for relevant colours and suitable graduations. To communicate colour Tria follows a highly effective, colour referencing system that is based on the human perception of colour. Each reference number indicates discrete levels of Hue, Saturation and Luminosity. The Hue establishes the colour, greens for example can be yellow-greens or blue-greens, Saturation shows how vivid the colour is, and Luminosity dictates how light or dark it is. A more detailed explanation is provided below:

Tria Colour Referencing

Digitally structured, meaningful, easy to understand references.

A Tria colour reference has 4 parts:

1) The Alpha Component

This is a 360° wheel made of 8 major colours. This determines the basic colour:
Red,Orange, Yellow,Green,Cyan,Blue, Violet or Magenta

2) Hue(First Digit, 1-9)

Each major colour is divided into 9 hue segments. Each hue segment within each major colour covers 5°. Using the diagram, a level 1 red (R1##) will be more magenta while a level 9 red (R9##) will be more orange. A level 5 red (R5##) would be right in the middle (not pinky, not orangy). In total there are 72 hue segments, which at 5° each make up the full 360° wheel across all major colours.

3) Saturation(Second Digit, 1-9)

Saturation determines how vivid a colour is and is divided into 9 equal steps. Each step is segmented from the centre (level 1) to the outer edge of the circle(level 9). A level 1 colour is almost grey with no colour (chroma). A level 9 colour will be fluorescent. R55# would be a right in the middle red - neither too grey or too vivid.

4) Luminosity(Third Digit, 1-9)

Luminosity determines how light or dark a colour is and is divided into 9 equal steps split vertically in the diagram (click on luminosity) from bottom (1) to top (9). A level 1 is virtually black. A level 9 is virtually white (pastels). R555 is middle of the road red, whereas R559 is a real baby pink.
