I love the colours in the Flare palette, if you have green eyes, it would be great for you. It has some shimmery and some mattes colours. Just like the other two palettes, I find the shimmer shadows tend to be better quality than the matte ones, I find some of the lighter colours tend to be chalky, in this palettes it's the far right colour that I have issues with.
Would I recommend this palette? If I had to choose 1 of the 3 Sigma eyeshadow palettes at this point, I like this one the most. Bare is nice, but most people have enough neutral shades already, and Flare offers something different.
