- Default exterior vertex color going in to the vertex shader appears to be
0.5, 0.5, 0.5. Because the pixel shader multiplies the modulated color by 2.0, the 0.5 effectively causes no change. Note that the default might only be the case for batch type C vertices, since some Northrend buildings seem to actually use vertex colors on exterior vertices.
