Fundamentals of Colours

These fundamentals of colours are the way a colour is described/how it is made.

Hue: this is the actual colour.

Hue

Saturation: this is the addition of grey to the hue (colour). The less saturation there is the more grey the colour will have and therefore it will look dull. If the saturation is set on the higher side the more purely the colour will be.

Saturation

Brightness: this is how much bright or dark the colour will look like. To look bright a hue needs to have white added to it, while to look dark needs to have black added to it.

Brightness

The more changes there will be in these fundamentals the more the colour will change in its appearing way.
