OUGD404 - Colour Principles

Systematic Colour 

Choice of colour can destroy the way we read out robust language, and make type illegible, like here:

Not everyone sees colour the same. What someone sees as a vivid yellow, someone else might see as slightly orange or green.

Reds have a high, strong wavelength, blue has a low one, and green is somewhere in between. 
Colour is about perception, and how we perceive colour. 

The eye contains two kind of receptors: rods and cones.
Rods interpret shades of grey, they only perceive tonal shades. Whereas cones allow the brain to perceive colour.
There are three types of cones, the first is sensitive to red-orange light, the second to green light, and the third to blue-violet light.

Primary colours are primary because they cannot be created by any other colour.

This is Johannes Itten's colour wheel.

When mixing primary and secondary colours together, it makes tertiary colours.

For a designer, the primary colours are RGB and CMY - K is a key colour, not a primary colour. 

CMY is physical - chemicals on photogenic paper, pigment
RGB is spectral colour, made from light

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

Subtractive colour
When mixing primary colours it reduces the value of them. When you mix primary CMY it makes RGB, so they are their secondary colours.

Additive Colour 
When you mix primaries of RGB, they make the secondary colours CMY.

Complimentary colours are those opposite each other in the colour wheel.

Task
For our task we had to lay out the objects we got told to bring in, which are a specific colour (I got Violet), and lay them out on the table to make a colour wheel. Here are some photos:

Hue is how we name a colour, how we refer to them. Whatever colour we are talking about we are referring to its hue.
We consider tone, saturation, light, brightness etc of a hue.

The luminance of a colour is when we start to consider the brightness and dullness of a colour.
Lighter/brighter colours reflect more light, whereas dull and darker colours absorb more light. 

In our colour groups we have to pick seven violet objects which are different - red violet, pink violet, blue violet, shiny, dark, light etc. 

Here are the seven objects. We ordered them from dark to light, and amongst those chose a lilac, deep violet, pink-violet, red-violet and a coated violet.

We then had to match up each colour using the Pantone Colour Reference System.
