Love what you did in that quilt.
Now about colors. Remember a lot of kids stuff is in primary/secondary colors. Not a thing wrong with that. In fact, IMO, a brighter colored quilt moves up in age with a kiddo better than a pastel quilt that might look baby-ish.
For her next quilt----------how about turquoise, purple, hot pink with maybe some chartreuse thrown in?
And there's nothing wrong with black and white with one or two primary colors added!
