This is one of the two BYS color changing polishes I nabbed over the summer before they got sold out. I think Erika might have gotten one too, but I'm not sure!This is really cool. It doesn't change from sunlight like the Del Sol polishes do, but rather from heat, so you get a really cool ombre look when you go into the cold or air conditioning :)
BYS Color Change Bright Purple, a photo by KitaRei on Flickr.
The color is named Bright Purple, and it changes from a deep but bright purple to a fuchsia pink with a subtle shimmer. It has a semi-matte finish (just as neon colors usually do) so for those of you who are like me, a topcoat will fix that ^_~ This is three coats, it is kind of sheer o if you don't want visible nail lines, I'd recommend an opaque base coat or a coat of white nail polish first :)
