Tria Markers
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.
