I put together a green top with a multicolored skirt, with green and two different reds as its main (non-black) colors.
So I took a little risk and took out three scarves in just those colors, and ended up putting the two reds right next to each other.
(Pardon the non-ideal picture: it was fairly close to candle-lighting, and I didn't want to keep fussing.)
I really like the way it turned out from most angles:
Please pardon my shirt tag in the next couple of photos...
I do like the mix of colors from the back, though. It feels dramatic and exciting, to me.
However, straight on sideways (is that a possible direction? What I mean is- how it looks from the side, as in the picture below), I'm not entirely sure. I think it might be improved by folding the second/dark red scarf one more time, so it doesn't project as far back.
