Design Principles, Colour Theory, Part Two

This week we looked into colour theory in a lot more detail. which included the contrast rules.

Contrast of Tone - the juxtaposition of light and ark values. Colour has tonal values, yellow is quite tonally light. 
You design against a grey colour because colours have different tonal values which change on different coloured backgrounds.

Contrast of Hue - colours that are close together and its hard to see the change, such as red and orange. But different ones like yellow to red is easier to see.

Contrast of Saturation - this is how dull or bright a colour is. Also known as chromatic value. Tints and shades change what we see

Contrast of Extension - this is the proportional field size in relation to weight of a colour, contrast is based on the proportion of colour. The way its put on page affects what colour jumps out more.

Contrast of Temperature - this is positioning warm and cold colours. Putting red next to a cooler red warms the first red up, changing the colour. Flat colours when put next to each other changes it, one edge is cooler while the other is warmer.

Complimentary Contrast - Opposite colours are trying to grab your attention. Such as Red Vs Green. Its the opposite contrast values that confuse the eye.

Simultaneous Contrast - When two colours are next to each other they vibrate which confuses the eye and the boundaries between the colours are blurred.
