Diffuse slot not showing colors correctly

[vanderloo]

Not sure when this started happening but my colors showing in the diffuse slots in most materials is showing black yet the material sample from the compact material editor are very green.
Long story short, I'm not getting accurate representations of diffuse colors in the diffuse slot of the material. See attachments.

Figured it out. in gamma/LUT setup, needed to check "affect color selector"
