Hue Luminance and Saturation (HLS) Model and Manipulating Colours

Pick and manipulate colours more easily

Normally in computers colours are described in terms of their Red, Green and Blue components. Whilst you can specify all displayable colours this way, it leaves something to be desired when it comes to picking a colour. For example, most people find it very difficult to determine what RGB values you would use to create a Pink or Brown colour (try it!). The HLS model provides a more intuitive method and enables you to create lighter/darker or more intense/less intense versions of colours very easily.
