This colour management system was standardised by the International Colour Consortium (ICC), and is now used in most computers.
The colour management module (CMM) is the workhorse of colour management, and is what performs all the calculations needed to translate from one colour space into another. Because monitors usually can display many more colours than a printer the CMM has to decide what to do with these out of gamut colours. If reproducing the colours on screen is impossible in print the CMM will convert the out of gamut colour to the closest approximation the printer can reproduce.

There are two ways to create colours
1. RGB
COLOUR SYSTEM Mixing Light ( Additive ) Create colour by blending RED GREEN BLUE light
sources Eg-[Red + Green] light = Yellow
[Green + Blue] light = White light The more light we add ,the brighter the colours mix
become This system applies only to devices employing light,
such as computer monitors and television sets.
2.CMYK COLOUR SYSTEM
Subtractive colour mixing Subtract the line from paper by adding more colours Used RED YELLOW BLUE Colour printers mixed them to get others hues As printing emerged, they will subsequently replaced
with CYAN MAGENTA YELLOW BLACK Enable printers to produce a wider variety of colours
on paper In subtractive color theory, all colors mix to yield black. In the print industry, cyan, magenta, yellow and black
are used as the primary colors. When mix all the colors, the result is gray

Colour circleFirst invented by Sir Issac Newton in 1666Based on RED YELLOW BLUEBlend to create others distinct hues
Cannot be formed by any combination of others colours
Others colours are derived from these 3 colours
Formed by mixing two primary colours
Mix primary colours together with secondary colours in order to create others 6 colours
Colour adjacent on colour wheel Create serene(=calm
&peaceful),comfortable mood Easy on eyes Choose 1 colour to dominate A second to support Third colour is used along with
(BLACK, WHITE, GRAY) as an accent Mainly, it is seen in nature
Opposing colour on wheel Very popular Naturally pleasing to eye Tricky to use in large doses Use 1 colour mostly Shouldn’t use both colour equally Bad for text
(=the main printed part of book / magazine,not the notes, pictures )
Called as Double Complementary 2 pairs of opposite colours Best use for foreground /
background / mixing everything in an area
Work best if let one colour be dominate
Pay attention to balance warm & cold
Never use 25% of each(like complementary don’t use 50% ,50%
Weak colour use them primarily And then use some brightness
colour Hard to pull off but can producing
pleasing result
2 colours adjacent to its complementary More creative freedom Feel lively, joyful Strong visual contrast , but has less
tension Good choice for beginners because
difficult to mess up
Equally distant each other on the wheel Hard to pull off Best for cartoon / surreal scenes Tend to be quite vibrant (=very bright &
strong ) even you use pale / unsaturated hue.
It mean “without colour”
Black & White rendering
Gray-Scale value Great for practising
rendering of value Contrast of painting
Medium
High Light

High Dark
Shade Adding black to a pure hue
Tones Adding grey to a pure hue
A hue which is on colour wheel mix with Black, White or Grey is called Monochromatic colour.
Monochromatic make the image become more details by changing its saturation
Great practice for value, contrast of painting [ same with ACHROMATIC ] Easy to manage, look balanced , visually appealing(=attractive) Creating atmospheric (=an exciting or emotional mood ) To highlight the most important element
Tint Adding white to a pure hue
Neutral = without colour Not on Colour Wheel
Formed by blending the colours on colour wheel with black, white & grey
Example : BLACK + WHITE = GREY Blending 2 complementary colours Blending all 3 primary colours BROWN
NEUTRAL
