Cyan light - magenta light - yellow light
blue + green= cyan, blue + red= magenta, green+ red = yellow
PIGMENT

29. ATTRIBUTES
We use them to define and describe
colour.
HUE
It is the name of the colours
that form the colour.
VALUE
It is the degree of lightness.
It depends on how much black
or white is in the mixture.
High value (tint)
Low value (shade)
SATURATION
It is the degree of purity.
It depends on the components of
its mixture
+ components = – purity
COLOUR
COMPLEMENTARY
Pairs of colours with
opposite characteristics in
its hue.
Yellow is complementary of blue.
Blue is formed with cyan. Blue hasn’t
got yellow.
Magenta is complementary of green.
Green is formed with cyan and
yellow. Green hasn’t got magenta.
Cyan, complementario del rojo

COLOUR SCHEMES OR COLOUR TABLES
Groups of colours according to their differemt attributes.
ACCORDING TO HUE
Hues move one into another as in scale.
COLOUR FAMILIES
Blue colour scheme: all the tones have cyan in their mixture
Red colour scheme: all the tones have magenta in their mixture
Yellow colour scheme: all the tones have yellow in their mixture
ACCORDING TO VALUE
We place tone values from lighter to darker

ACCORDING TO SATURATION
Pure hues become greyer and greyer
SATURATION FAMILIES

ACCORDING TO ITS TEMPERATURE
Scale ofcool hues: blue families, violets, blue-greens…
Scale of warm hues: yellow families, oranges, reds…
