A few days ago I chose a color for a part in an assembly that I didn't want, so I "threw" it off to a blank part of the screen. After I did that the entire assembly turned that color (I think it's brass). SW2014 and earlier would let me throw off colors like that, but with SW2015 it's acting different. If I save the assembly, brass color and all, it returns to normal colors when I open it back up again. Later, after some operation, the brass color comes back again until I do another quit and reload. Does anybody know where this color is hiding? I can't find it, and it's getting annoying.
