This is the prettiest blue ever! I love it! I used 2 coats here. But this is so pigmented I could have gotten away with just 1 coat! In the bottle this looks like it might be a dup for Barielle's Berry Blue, but I haven't tried that one yet ( I have too many untried's in my stash!). I don't now what else I can say about this one it's just so perfect! I think the pics speak for themselves. This was with no base, no top.
