I love quads and I really didn't have any similar colors, so I caved and bought it off here.
I already had Vanilla, but it is a staple for me, so that was worth it.
Hey is a gorgeous color (my favorite of the whole quad), but I feel like it could be made by layering some other colors.
Pink Venus....well...pink shadows just don't like me, and mine came off pretty sheer and had to really be layered to get any payoff, which proceeded to fade rather quickly. It kind of irritated me, but it the same with any pink shadow on me.
Howzat was really nice and a lovely color. For me, this was close with Hey as to which is my favorite.
I think that if you don't have any of these colors, it might be worth it to buy the quad. But if you aren't sure or already have a lot of these colors, I would probably pass on it. HTHS!
