Lets see, the things highest on my wishlist of desired recolors are...
Rosamund's Revenge - I love this item sooo much, its just lovely. But I don't use black often! I'd love to see a white/creme recolor, and the third color could be pale blue, silver, bronze, chocolate brown... Well, as long as the base colors are white and creme I'd be happy with any other color.
Petit Cherie - It's such a wonderful item that doesn't get enough love! As much as I think it's perfect as it is, I wouldn't be opposed to a recolor where the green is pale blue.
Runcible Spoon - White and pale blue for the girls, white and chocolate brown for the guys. Haha, can you tell I love pale blue?
And another note, pretty much any of the cutesy girly frilly items in pale blue would make me happy. Its my favorite color and I want to see more of it!
