“weapons of all kinds, musical organs,
bright colours and ornamental
appendages, have all been indirectly
gained by the one sex or the other,
through the exertion of choice, the
influence of love and jealousy”
C. Darwin, 1871.

Why do humans have colour vision?

Many different species
possess complex colour vision
and use colour displays for
protection, communication,
and attracting mates.
Evidence indicates that
primate trichromatic colour
vision evolved in the context
of food detection, and was
later co-opted by other
behaviours, like mate choice.
Human colour vision is an
inherited trait from our
primate ancestors.

Do we all see the same colours?
Most modern
languages include
11 ‘basic’ colours:
black, white, grey,
red, orange,
yellow, green,
blue, purple, pink,
and brown

The Yolngu (Australia) do not
have a (explicit) distinction for
design and colour.
Brilliance is the most
important property in the
Yolngu aesthetic system.
The Candoshi (Amazonia) do
not seem to have a concept
of colour or any colour words.
They use comparisons to
describe colours, for instance
they would use ‘like ripe fruit’
to say red, or ‘like tar’ to
mean black.

Humans are actually able
perceive up to millions of
different shades, but these are
generally grouped culturally
into so-called ‘basic colour’
categories.
Perception is not only the
result of how sensory data
are interpreted by the brain,
which may vary among
people, but is also influenced
by factors like distance, angle,
lighting, background, and even
the proximity of other colours.
Do we all see the same colours?

There are some cross-cultural
similarities regarding the
emotional effects of colour.
Red, yellow, orange often evoke
agitation and stimulation,
whereas blue-green give a feeling
of focus and calm.
These emotional associations
might explain that babies seek
sensory stimulation, while adults
favour calming colours.
If colour biases evolved from
primate food-seeking behaviour,
red-orange colours, associated
with ripe fruit, would induce
arousal and alertness, whereas
green-blue colours reminiscent of
foliage and skies might induce
rest behaviour.

Some conclusions…
L MENDOZA STRAFFON - ICA COLOUR DAY
Colour vision was
inherited from our
primate ancestors.
Humans since their origin
have been concerned
with ways of
incorporating colour into
their lives, and beyond.
Our species has evolved
unique and extraordinary
strategies to exploit
colour culturally, in many
different contexts.
Our ancestral interest in
colour likely drove the
evolution of human
aesthetic cognition and
artistic behaviour.
