render of a white object is gray? I have got a interesting effect while rendering a white coffee mug.




When I render this white mug it appears more grey than white. I have a glossy ~10% and a defuse ~90% shader on this. Both shaders have the color set to white. But those pictures do not look as it should, do they? They are more grey than white.

More pictures and the blend on google drive.
The color of your cup depends on the color of the background, how much light you have in your scene, and the amount of objects you have in your scene. If you add a lamp or an object emitting light and set the value to at least 5, you will get a white mug
