ColourPop Interstellar is a moderately warm-toned, medium pink with a matte finish. It is a limited edition blush that retails for $8.00 and contains 0.13 oz.
ColourPop Interstellar Pressed Powder Blush ($7.00 for 0.21 oz.) is a medium-dark pink with strong, warm undertones and a matte finish. It had medium to semi-opaque, buildable color coverage that applied fairly evenly and smoothly to bare skin, though I felt like it was a little harder to diffuse and blend out over bare skin (but easier over matte foundation).
The texture was soft, silky, and lightly powdery but seemed less powdery than some of the brand's blushes released in the past. The color darkened a bit when applied to bare skin, too, so this shade--and the formula in general--tend to apply easiest and retain truer-to-pan color applied over just-powdered/more matte skin. It wore well for eight hours before fading visibly.
