lizzie3, are you purposely avoiding darks in your choices? In Bonnie's photos in the introduction, I read her purple and green as darks, her constant and yellows as mediums, her lavender as a medium light, and light neutrals. I would try to stick with those value relationships if you want to duplicate the effect of her pattern.
The other thing is, that judging by what we've seen so far with people's units, you will want the constant to be a different hue than the other colors. I would not make the constant purple if purple is one of your other colors, but would choose something that really pops with the other colors. I see the constant as a highlight color, meaning it is used sparingly but really stands out. So I think the second option you listed, with the pink constant, sounds better than the first.
As far as the photo, I don't think the blue has too much white to use as Bonnie's green, because the background is quite dark.
Beautiful units, JeanneS and AlvaStitcher!
