Some changes:

The profile changed: the sqrt changed to abs, the smooth limit changed to 0.5

The value input of the hsv color shader is calculated in the interval 0.1..6/7

The displcament multiplier is the hsv shader weighed by 0.4, 0.4, 0.2.

Elimination of the mix shader(replaced by a dot shader with the about weights,

seems to be more efficient.
