I kept switching from a light red or sky blue, to an undersaturated blue, to a white, to a dark green, to black, to... well you get the picture. On one hand a red hue was the safe bet, but when I slapped that blue on there, there was something nice about it (at least to me). I kept stressing out whether people will get thrown off by it too much. Anyway, I ended up going with the blue of the sky. It makes for a nice highlight, and connects the panel to everything else. I think what really clinched it for me was that it also signified what she's looking at (the sky outside). Now I don't know if anybody's gonna even get that, but in my head (for now) it makes sense. That blue color is also the perfect lead in for the next page.
Well, at least if I can get it to work! Tune in!
