CH2RGB starts like:
#macro CH2RGB (H)
   #local H = mod(H, 360);
   #local H = (H < 0 ? H+360 : H);
   #switch (H)

Guess that the H used both as a local and an argument of the macro was
not a so smart idea: it ends up modifiying the original argument.

It should have been something like

#macro CH2RGB (H_not_modified)
   #local H = mod(H_not_modified, 360);
   #local H = (H < 0 ? H+360 : H);
   #switch (H)

Just my 0.02€, tax not included.
