Hue, saturation, and brightness are characteristics of colours.
Hue is another word for colour. The hue (colour) is the dominant wavelength that we see, for example: red, blue, green.
Saturation is the intensity of the colour. It is how vivid and pure a colour is. This is determined by the amount of grey colour that is present.
For example, when grey colour fully exists in red colour, then the red colour is not saturated. It is de-saturated.
When there is no grey colour at all, rather only the red colour exists, then the red is highly saturated – it is pure and vivid.
Brightness is how much dark (black) or light (white) exist in a colour. For example, when full black is present in red colour, then the red is not bright. It is dark.
When full white dominants, then the red colour is fully bright.
Hue, saturation and brightness can be represented as a cone.
