2068	Transparency retained when coloring	olibclarke@…	Tom Goddard	"{{{
The following bug report has been submitted:

Description
Hi,

Not sure if this is a bug but it seems unexpected to me. If I define a color that has some degree of transparency (e.g. color name part_invisible 0,0,0,10), and use that to color a model, when I subsequently apply a color that doesn't have tranparency (e.g. a built in color like cornflower blue), the model retains the transparency from the first color. This is not how it worked in Chimera, and is not how I would expect it to work - is this the intended behavior?

Cheers
Oli
