The only one I don't like much is lilac. I do like pink slightly better than white, but only because it is a peach/salmon pink, rather than a hot pink or neon pink.
In general, I like unnatural hair colors as long as they aren't neon, and they aren't too bright.

White will be the easiest to keep. The others will look nice for a maximum of 2 weeks before they fade too much
