OUGD404- Design Principles- Colour Theory 1

SYSTEMATIC COLOUR (Part 1)
introduction to colour principles

An eye for colour tutorial 

I found this video that explains  how color is perceived into different environments. The way the human eye works and understands light.

Colour is about perception. We perceive colour through light.

Blue- Lower, shorter wave lenghts 

Red- Higher, longer wave lengths

Green- In between red and blue

• The eye contains two kinds of

receptors: rods and cones.


• While the rods convey shades of gray,

the cones allow the brain to perceive

colours .


• Of the three types of cones, the first is

sensitive to red-orange light, the

second to green light and the third to

blue-violet light.

When a single cone is stimulated, the brain perceives the corresponding colour. 

•If our green cones are stimulated, we see "green".
•If our red-orange cones are stimulated, we see "red".
•If both our green and red-orange cones are simultaneously stimulated, our perception is yellow.

Colour Wheel

Primary colours- Primary colours can not be made by mixing other colours

Secondary Colours- Secondary colours can be made by mixing two primary colours

Tertiary Colours- Tertiary colours are the breath of colours that exist

Complimentary colours- Complimentary colours are opposite each other on the colour wheel

Colour Theory: The Truth About The Colour Wheel Tutorial

Colour Modes

CMYK

CMYK colour mode is for print

CMY are the primary colours

Black is the key colour

RGB

RGB colour mode is for screen

Spectral colour (Made of light)

•The eye cannot differentiate between spectral yellow, and some combination of red and green.

•The same effect accounts for our perception of cyan, magenta, and the other in-between spectral colours.

Subtractive colour

Primary Colours- CMY

Secondary Colours- RGB

Neutral Colour- Black

 Additive colour

Primary Colours- RGB

Secondary Colours- CMY

Neutral Colour- White

After part 1 of the presentation we were asked to gather the coloured objects we had brought in. I was given the colour:

GREEN

We got into groups of the same colour and created a colour wheel with the objects we had brought in. We chose to categorise them from blue/green, green, green/yellow. This was more difficult than I expected. Some of the different factors that effected our decisions were light, mat/coated surfaces and materials. It was interesting to see that we could only categorise them when there is another colour to compare it to.

Colour Theory: Hue and Saturation Tutorial

CHROMATIC VALUE

=

HUE  +  TONE  +  SATURATION

Hue 

Chromatic Value- how the purple is affected by saturation

Shade, Tones, Tint, Luminance 

Shade- Desaturation through chromatic value

Tint- Desaturation through tonal value

Tones- Desaturation through both

Pantone

Pantone is an accurate system of every colour that has been made. This means you can identify any colour to a pantone swatch and get a true match.

For the second task we had to choose 7 of our objects reflecting the darkest green, middle,

lightest, brightest, dullest, bluest and yellowest. We had to match the colours to colours in

the pantone guides.
