+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.
