RGB color model is used from image capturing chip and from display to define the colors.
But image capturing chip and display have different sensivities on each channel.
Because of this there has to be a compensation, means RGB is never the same as RGB.
Linear RGB
RGB values are calculated as linear RGB values, as the sensor chip delivers linear RGB values. Advantage
of the linear RGB value is the linear relation between physical impact and RGB value.
Example: Doubling the shutter time leads to doubling of RGB values, if all other illumination conditions
remain stable.
4.6.7.8.2 Color model HSV
HSV color model is the most similar to describe what the human eye sees.

H (hue) stands for the angle on the color circle (e. g. 0° = red, 120° = green, 240° = blue)
