I get that the NPC profile pictures are circled in green belts for "good" and red belts for "bad", but there is no actual legend stating that as a convention. Also, the red/green combination provides an extremely poor colour contrast for those with protanopia (red/green colour deficiency). Perhaps red and blue would be better colour choices?
Realistically, I would prefer to do away with those belts altogether as they take up so much of the image. I'd rather have the image size increased for these thumbnails. Also, for those that aren't in the NPC Portraits handouts, having the coloured belts means I can't quickly show the page to players, because they'll be quick to realize that what the difference between the two colours represents.
