Model Silhouette is not the expected color

Note that when Forestgreen is selected for the model and the silhouette, the colors look fairly different - the silhouette is much lighter. When Lime is selected for both, they look about the same. This appears to be due to the fact that Lime is a more saturated color (#228B22 vs #00FF00). This lightening effect holds true in general, not just for these colors. It is not clear from looking at the API why this would be the case.

#7563 should fix it.

When the color blend mode is Replace the colors should now be identical. It also looks better for the highlight and mix modes.

Tested out the fix - looks good. Thanks.
