Hi Markus, We're glad you like the worms! Unfortunately, there is no option to change the color smoothly along the worm instead of using a single color per residue segment. This is a current limitation of ribbon coloring in general (not just worms). Sorry about that. In the future we would like to add this capability of gradually changing the ribbon color from residue to residue. I'll make sure it goes on the "to do" list of requested features.

The worm tool has many wonderful options to adjust the ribbon size according to the b-factor or occupancy, including the options of abruptly changing the radius for each residue or a smooth change. It also allows to change the colors varying on the values used. I can not find an option to display smooth transitions for the colors that would correspond to the smooth transition of the radius. All I see is the color changing abruptly for each residue. Is a smooth color transition available?
Sincerely,
Markus
