Colour can be destructive, making things illegible. Colour has to be used correctly.
Colour based on perception, it travels to us through waves.
EYES
The eye contains 2 kinds of receptors.
Rods and cones
While the rods convey shades of grey, the cones allow the brain to perceive colours.
Of the 3 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 stimulates 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
Primary colours, Red, yellow, blue
mixing 2 primary colours gives you a secondary colour
Secondary colours, orange, green, violet
Tertiary, to get a tertiary you mix together a primary and secondary.
Red, Green, Blue, RGB spectural colour
Cyan, magenta, yellow are primary colours in CMYK, secondary colours are RGB
Subtracted colour, when mixing primary colours you remove the colour values. CMYK are secondary colours: INK
Additive colour, when adding Red, Green, Blue it forms white: LIGHT
Complimentary colours, colours opposite on the colour wheel
Lecture Part 2
Chromatic Value = Hue + Tone + Saturation
Hue is the name we give to colour, to distinguish between them, e.g. bluey green, green and yellowy green
Luminance is how bright something is
SHADE
Darker colours absorb a lot of light
Lighter colours reflect more light
TINT, reducing the chromatic value, haves more luminance
TONES, comes from desaturating a colour
Colours change depending on what is surrounding them and what they can be compared against, as shown below. Our perception of a colour changes when a colour is put next to it , so what might of been a red before might change to a darker more violet red after.
As can be seen here despite the fact the outside colour is all the same but it seems to change when you move past the middle point
For a task we were asked to layout all the colours we had collected in a colour wheel type layout, ordering them from the most yellow orange to the most red orange. The selection of orange objects below are what i brought in.
This is the layout we as a group arranged into the different tones of each colour.
This is the final outcome, as can be seen each group looked at each object and decided whether or not it had more of one colour that was next to it in the colour wheel, for example in my group i looked at a object and decided it had a lot of yellow in it so put it at the end where the yellow joined on to the orange.
After this we were asked to select 7 objects that displayed the most yellow, most red, the darkest, the lightest, the palest, dullest and the standard orange. With each of these objects we used the pantone set we were introduced too to match them up with the closest colours.
Our pantone selection was:
MOST YELLOW - Shavers, Pantone 123c,
15pts Pantone Yellow 93.8
1pt Pantone Warm Red 6.2
MOST RED - Nail Varnish, Pantone 173c
12pts Warm Red 72.2
4pts Yellow 24.3
1/2 Black 3.0
BRIGHTEST - Glove, Pantone 1645c
10pts Warm Red 62.5
6pts Yellow 37.5
DARKEST - Reeses, Pantone 1655c
10pts Warm Red 62.5
6pts Yellow 37.5
PALEST - Ticket, Pantone 712m
4pts or .021 3.0
1/8pt Black .06

DULLEST - T - Shirt, Pantone 1635m
21/2 pts Warm Red 15.6
11/2 pts Yellow 9.4
12pts Trans Wit 75.0
