******************
Packed HSV formats
******************
Description
===========
The *hue* (h) is measured in degrees, the equivalence between degrees and LSBs
depends on the hsv-encoding used, see :ref:`colorspaces`.
The *saturation* (s) and the *value* (v) are measured in percentage of the
cylinder: 0 being the smallest value and 255 the maximum.
The values are packed in 24 or 32 bit formats.
