I can sort of confirm that, though I don't see it like a yellow blob like in the screenshot - testfiles are always useful here. Symptom is that the material does not get refreshed. Will check it out.

Well I also don't get this bright orange color, but I guess this comes from an orange material + deleting any lamps in the scene?

@Psy-Fi, I just thought it is very intuitive, to repeat it, just:

start blender,
swtich to Texture Mode,
then try changing the Diffuse color of the default cube's material.

The reason I don't upload .blend file this time is that it will refresh when you reload it, which makes it useless (and probably misleading). But sorry if the screenshot is sort of misleading.

@JulianEisel, the orange color is a previous color displayed before refreshing, nothing fancy. :) And yeah, I thnk I temporally used shadeless viewport shading in that screenshot.

Are you on GLSL or Multitexture?

Since introduction of Material display for Cycles, all this stuff is very weird.

When we are using GLSL, diffuse color is taken into account by texture display. And it seems that there is no difference between texture display and material display for BI. In both cases, texture colors are mixed with diffuse color.

For Cycles, it is not diffuse color that is taken into account but viewport color until there is a texture node in material.
At this moment, there is no mix. It looks more like texture display for BI when using multitexture or more like Texture Solid.

I suppose that even with GLSL. It should work for BI like for Cycles.
Diffuse Color when no texture. Texture Colors when texture is used in material.

That's why new viewport project is worked on, to make those display modes more transparent. But this is not really relevant to this bug (missing updates)
