I like 5 & 2 for the same reasons yet they are quite different (gosh, I sound like an Ann Rice book). Pic 5 The patina and orange lettering are slightly absorbed by the backdrop but the blue lines of the frame separate the bike from its backdrop. Pic 2 does the same thing. It has blue and lighter hues similar to the gray of the backdrop that the backdrop "pulls" from the frame. The orange hues of the patina pull the frame lines back out of the background to make a statement. So the question to me would be which color would I want to be more prominent? Black is black, it looks good in both scenes and sets the visual boundaries of a great looking bike. I must be tired, I'm rambling.....
