From what I recall, Val said something like "I'm getting tired of black & red everywhere. But I've really been into Orange lately." That was a paraphrase, but he also asked about blue, and a bunch of us weighed in. Then he showed us a picture of the retail boxes, and it was pretty much game over (despite a few photoshop efforts).
The Sun Orange shields! What a combo! I have it and it's very nice. But really, I don't think there's a colour combo that's wrong (Unless you got the shadows, red doesn't really 'match' with much very well)
I'm really digging the matte black too. It's so sexy, and NOT flashy. My shiny Sun Orange shields give it a nice flare. I'm thinking of getting some more colour combos with my Matte Black M-100s; purple audio only cable and a set of green custom shields, the combination of orange, green and purple just appeals to me so much.
