Hi Michael,

that would be super awesome if you could do that and HSV color space would be perfect.

For the second question, thanks for the info, but I think workflow wise it is not so pratical,
like what I have suggested. For example if one has many splines or objects, select groups
of them each time, to colorize them with your script individually.

Best regards
Stefan
