I had a 12 Tuxedo Scab with the factory graphics.
They were barely noticeable. In fact, most people never noticed them, especially on the hood.
The factory color wash a mix of matte and semi glossy, again that was even less of a contrast and it too was hardly noticeable the graphics were two tone. At night or overcast or cloudy nothing. In bright sunny days, still hardly noticeable. Do NOT Go with the black, whether matte,semi,or gloss, IMO a waste of $$$, useless and unnoticeable. Go with the gray similar to the original fender flare OEM color, in matte, semi or gloss, better a combo of matte n glossy ,even though your fender flares aren't OEM color now. The gray will not stand out much at all, but you will be able to notice em. IMO, exactly how you wanted.
