Illamasqua Burst is a very cool-toned, dark teal with a matte finish. It is a permanent eyeshadow.
Illamasqua Burst Eyeshadow ($20.00 for 0.07 oz.) is described as a "blue-green." It's a medium-dark that's just barely been kissed by tones of teal. It's more blue than it is teal or green, but it's not just blue. Tarina Tarantino Ozma is a bit similar in color, but it has a frosted finish, so it ends up looking different. MAC Cool Heat is a little more teal and has a subtle sparkle. Urban Decay Haight is bluer. Inglot #338 is a bit darker.
