Moment of decision: which color do you prefer for the OpenSprinkler enclosure?

The final sample of the injection molded enclosure has arrived. Very exciting! The moment of decision: I’ve got three samples, each with a slightly different color. I’ve taken a few picture of all three side by side. The differences are subtle, but basically the first one (left) is more gray-ish, the second one (middle) is closer to milk white, the third one (right) is closer to pure white. Please vote for your favorite color in the comments section below (you can either use 1, 2, 3, or left, middle, right, or anything un-ambigious). I’ve only got a couple of days to give them my final decision, so please vote as quickly as you can. Thanks!
