HSV explained

There are many google pages which explain HSV, so this is a very brief introduction.

 

Most ways of specifying color are based on three numbers. And example is RGB (Red intensity, Green intensity and Blue intensity). HSV is easier to understand and manipulate than RGB, it is more intuitive.

 

H = Hue = the base color, for example green or purple.
S = Saturation = the strength of a color, for example a pastel blue has less saturation than a sky blue.
V = Value = brightness.

 

(In addition RansenScan has a Contrast setting.) Here are some examples:
