I hope no one is disappointed by the lack of a very hot polish that was released by Chanel this year, Mimosa. I don't have it to compare, but if you want to see that comparison, Ivana showed me a link that compares Catrice Bye Bye Birdy and the Chanel. They're not dupes, Chanel Mimosa has a darker, more yellow base compared to the Catrice (this is what I can gather from looking at the pictures).
Anyway, I only have two yellows in my stash. I think. So I decided to compare for the sake of comparing. I knew there wouldn't be dupes because one has hidden shimmer and the other two are cremes.
I did 3 coats of everything. I prefer the brush and formula on the China Glaze polishes but again, not dupes and if you like yellow you might like (and feel the need to own) all of them.
Catrice Bye Bye Birdy, China Glaze Lemon Fizz, Catrice Bye Bye Birdy, China Glaze Happy Go Lucky
I hope this gives you a clearer indication of what shade of yellow Catrice Bye Bye Birdy is.
I'm not a huge fan of yellows, so I don't have many. I could have 3 yellows and a million reds. I like red (:
