Diamond Sky is a subdued blue with a hint of teal (more blue than teal) with a frosted finish and cool undertones. The color payoff was fantastic, and this was the easiest shade to work–no problem achieving rich color on the lid, and the texture was soft enough to be easy to blend but not so soft that it was powdery. Tom Ford Emerald Lust #3 is slightly more teal. Urban Decay Unhinged is similar but more subdued–not as bright. Urban Decay Deep End is a smidgen darker and more teal in color. Tarina Tarantino Ozma is very similar. theBalm Open to Offers Olwen is very comparable. Urban Decay Haight is darker and bluer.
