Hi Karsten,

I had years ago done many things like this with Shade3D and a Gradient plug-in,
but unfortunately I no longer have that data to show, due to a harddisc crash,
while not keeping back-ups.

To explain it again: A user should have the option via a script to select two
colors, a starting and an end color (HSV color space, like Michael suggested)
so that he/she will have later a gradient on prior selected splines or objects
as style colors applied.

This would be IMHO very appreciated (at least by me) for people doing
mathematical line drawings with MoI or when used for example on arrayed
solids or surfaces etc. Possibilities are endless with this colorizing option.

Best regards
Stefan
