2.1 Color Spaces

### 2.1.3 HSV

The RGB color space has a fundamental disadvantage. It is not easy for a normal user to define a color in the terms of red, green and blue.

HSV helps here a bit. It contains the components hue, saturation and value. Hue defines which color to use: red, yellow, green, blue, ... Saturation defines the pureness of the color: less saturation results in a more grayish color. Value defines the brightness of the color.
