On my
NHB the front and rear bumpers are a greyer black and the rest is a bluer black in bright sunlight. I noticed the bumpers on other colours are greyer / darker in strong sunlight. Other manufacturers don't seem to have the same problem. My worry would be if you had to have an adjoining panel resprayed and ended up with three shades. I also wonder about Milano Red and whether the bumpers look very different at night when different shades of red tend to show up.
