Texture colors wrong in material

Hi, sorry if this has been asked before, but I googled for an hour before posting and couldn't find the answer. Maybe I can't figure out how to phrase the question right?

Anyway, I have a texture (a PSD file) and when assigned to a material using the standard shader, certain colors are completely wrong. Tan shows up as white, and I can't figure out what I'm doing wrong. Other textures look right, and I THINK I have the same material settings, and it's driving me crazy.

Base texture:

Material result/setting:


Thanks in advance!
