All models appear gray in main viewport

orionnautilus

All models brought into the scene appear gray when I hav smooth shaded mode enabled. When I enable cartoon shaded it displays the base color. The Aux viewport displays the models correctly irrespective of the model enabled. Models render correctly. It is just the scene setup that is the issue.

Toon shaded uses textures, not the base colour. Smooth Shaded uses just the base/diffuse colour, no textures.
