forgetting about the white shirt- blue shirt thing…
and i know this might sound silly if you’re not in the business, but if the situation is as portrayed, meaning that it looks like a sea of black and white and one colored sticking out,
one of the first things any graphic designer would do, is change it to a white shirt or crop him out, just because if you don’t, when you look at he picture, your eye is (subconsciously or consciously) drawn to the colored shirt
just by the mere fact that it is different.
