Systematic Colour-Part 1
Introduction to colour principles
Tone effects legibility when you get it wrong, (pale blue, Green text on red background) Deconstructs the text to what we are used to. Colour can destroy the hardwork if you do it wrong,
-We dont all see colour the same. Philisophical nightmare.
-Physics of optics, the science in how you see light, if something is blue higher and shorter wavelength. Red high and long wavelength. Based on light and how we see it.
-The eye contains two kinds of receptors called rods and cones
-While the rods convey shades of grey, the cones allow the brain to percieve colour.
-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 percieves the corresponding colour,
-If our green cones are stimulated, we see "green".
-If both our green and red-orange cones are simultaneously stimulated, our perception is yellow.
Terms in relation to colour
Primary-Red, Yellow,Green (cant make those colours from any other colour)
Secondary- Violet, Green, Orange (can make thses colours with other colours mixed)
Mix two primarys to get the secondary colours
Tertiary- Bredth of other colours between the Primary and Secondary. The intermediate.
Colour Modes
RGB-On scree, colours projected by light
CYMK- Cyan, Magenta, Yellow,Black- Black classed as primary but only as a key colour. Black defines shade and tones
Important difference- CYMK-Physical, pigments inks etc
RGB-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.
-Because of this physiological response, the eye can be "fooled" into seeing the full range of visible colours through the proportionate adjustment of just three colours : Red,Green and Blue.
-The perception of colour is all the same thing.
Subtractive Colour- When mixed you get black-(RGB-Secondary, CMYK-Primary)
Additive colours- Light RGB you get white
Interelated all based from the ability to see light
Blue weakest length which is why the sky is blue, reflected, refracted and bounced about, we only percieve it blue because of optics.
Colour wheel systematises the colours, explains the colour system Johanna sittens colour wheel.
Complimentary colours- The direct optical colour:
Red- GREEN
Blue-ORANGE
Yellow-VIOLET
Optically directly opposed each other, Destroy each other.
Yellow + Violet
Orange + Blue
Red + Green
=All equal to a neutral Grey
The Violet, Blue, Green are all complimentry colours which cancels the colours out.
Tertiary Complimentary colours when mixed
Mixing all primarys together.
RGB light mixed in different proportions gives us all the colours

Systematic Colour Part 2
Dimensions of colour
Chromatic Value (system of how we understand colour)
=
Hue + Tone + Saturation
Colour wheel has the same chromatic value, however the hue changes
Colour relates to the whole chromatic value
Hue has an affect from the other elements
Tone and Saturation needs to be considered when talking about hue.
Chromatic value can be affected by Luminence - Bright or Dull when you saturate a colour it changes the illuminence
Dull colours absorb light
Bright colours reflect light
Luminence with yellow is bright yellow increasing the luminence reflects more light and goes white but classes as a tint. Chromatic value low, high luminence.
All three elements you get tones inbetween.
Shade, tones, tints address the dimensions of colour
Purple- Gets desaturated pushes it to grey- 1 Dimension
-Opposite dimension goes to black
-Keeping chromatic value but push it to another colour
-Take violet out of it push it to blue- Desaturate
All of those working togther gives you seven points
When you cant see any other colours to compare with then it is the reddest, however as soon as you put another red that is more brighter then the origninal red looks to be more brown,
When a colour has a higher value next to another colour, the colours change to how you see it,
A colour sat next to two different colours the colour looks different
Problem in how we as Graphic Designers talk about colour and use it
Pantone is... your best friend
Can use it for both print and on screen
Range of colours that can standardize
Each has their own colour code. Extensive system of all colours ever discovered.
Not just man made colour
READ, MATCH,COMPARE
Specify colours using Pantone
If you want to work with colour in design it has to be... Systematic
Task 1
After placing all the coloured items down we had to choose Seven items that are defined by their chromatic Value. Tints and Shades, Brightest to Dullest
My colour was Violet
