GeForce GTX 560 SE
Short description of error
The color for edges with a bevel weight is the same as the one for selected edges (default orange). The color property of bevel weight is non-existant in the user preferences. It draws its color from the "selected edge color" property. If one changes the color for selected edges, the color of beveled edges is also for that color. All other edge properties (crease, active, seam, sharp, etc.) can all be set to a unique color except bevel weight.
I was wondering if this shouldn't be filed as a feature request, but I reasoned that it should be considered a bug, because it makes bevel-weighted edges appear selected even though they are not. In fact, there is no way to distinguish a selected edge from an edge with a bevel weight.
