Materials not rendering I have been searching online for the answer to this for a few hours now and I just can't get this resolved on my own.

The materials are not showing up in the final render, they show as gray scale but show up colored in everything else. I have made sure the materials are made in Cycles render and that there are no over riding of materials in the renderlayers tab.
You are filtering color channels in the Image Viewer, currently only the red channel is being displayed.

Return to Color and Alpha mode, your image is fine, no need to re-render.
