Could someone explain why the carpet in this image becomes blue? And maybe know a way to fix it?

I would imagine it's something to do with the sky lighting (daylight system) casting slightly blue light? But why isn't the door blue then?

On the material carpet, have you applied a texture?
If yes, have you assigned a uvmap at the carpet?

Sorry for my terrificant english! :roll:

It's just a procedural, with no textures (and no uv), but it's also blue if it's just a plain white diffuse material.

It almost looks like it's an emitter. :?

Magog: Why would the uv map have anything to do with it? It's a simple plane.

With texture lighting it doesn't turn blue, but I'd like to use the daylight system.

Just switch the material to a plain diffuse and make sure there is nothing on the material's emission channel...
It might have accidentally imported it as an emitter.

It does the same with a normal diffuse material with no emitter. I made the light come in from a different angle and that helped. It seems that it only turns blue if the light comes almost straight above through a window in the roof.

Are you lighting it with an emitter? If so, try a blackbody emission. You can change the color temperature to make it more reddish and less blue.

I think the issue is that your model is imported way too large and the default configuration without global illumination on for editing (eg directlighting) has it's default AO ray length too small.
If you switch to pathtracing it should render fine, or, for editing or previewing, either import in the correct scale, or change the AO length parameter in the directlighting kernel settings in the preview configuration.
