Color difference between 2 objects in Object Mode/Solid View Blender 2.79
Two objects with identical material settings and no texture.
Viewed in Object Mode/Solid View the one on the left has a dark, bluish tint. The two look identical in other views and render with identical colors. But why the different colors in Solid View?  A minor but nagging and annoying nuisance. Much thanks from a newbie.
The left object doesn´t have average normals. I can see it because on the bottom there's a black face and there's a different color on the object.
Enter edit mode. Select all faces, press CTRL+N to average normals. Your object is now of the same color than the right one.
