Q

Pure versus impure colour

A

Pure colour or colours of the visible light spectrum

Impure colours are colours washed out by various other wavelengths of light

16
Q

What does LAB stand for

A

L = luminance with black at zero and white at 100

A = Red/green axis

B - Yellow/blue axis

17
Q

What does the graph for the LAB model look like

A

A grey pole with a colour wheel in the middle

18
Q

What does the HSL colour model stand for

A

H is Hue

S is saturation

L is lightness

19
Q

What does the HSL colour model look like

A

Like the SLC

Hue is curved line
Saturation is horizontal line
Lightness is vertical line going up

20
Q

What is the RGB colour model look like

A

A cube with colours

Red is the top
Green is bottom left
Blue is bottom right

21
Q

What are six factors that influence how we see colour

A
  1. Light environment
  2. Surface reflectance
  3. Colour temperature
  4. Surrounding colours
  5. Colour juxtaposition
  6. Colour constancy
22
Q

What is light environment

A

We need a minimum amount of light to see colour properly

the purkinje effect

23
Q

What is the purkinje effect

A

The light sensitivity of a human I shift towards blue as the environment gets darker

24
Q

In terms of light environment what happens when there’s too much light

A

Too much light makes colours bloom

and makes them white

25
Q

What is surface reflectance

A

Colour is light reflecting off of the surface

matte vs reflective surface will reflect more or less light and colour

26
Q

What is colour temperature

A

Higher colour temperature will saturate blue objects more

27
Q

What is surrounding colours

A

Colours will appear differently based on the colours next to them

Also referred to as simultaneous contrast

28
Q

What is simultaneous contrast

A

It’s the way that surrounding colours will affect the main colour

29
Q

What is colour juxtaposition

A

Creating colour vibrations by placing two contrasting colours next to each other

30
Q

What is colour vibration also referred to as

A

aliasing or the moire effect

31
Q

What are the six colour harmonies

A
  1. Monochromatic
  2. Analogous
  3. Triadic
  4. complimentary
  5. split complimentary
  6. tetratic (double complimentary)
32
Q

What is a monochromatic Harmony 3

A

Single hue

Helps isolate subjects by limiting the focus to line and shape

Atmospheric

33
Q

what is analogous colour harmony 3

A

Neighbouring Hues

Easy on the eye

Common in nature

34
Q

What is triadic colour harmony

2

A

Equidistant hues

Often seen in cartoons

35
Q

What is complementary colour harmonies

3

A

Opposing Hues

Very common

Pleasing to the eye

36
Q

What is split complementary Harmony 2

A

Similar to complementary

Has a wider more flexible pallet

37
Q

What is a tetratic colour harmony

1

A

Two pairs of opposing hues
