Surratt Halogram Collections The darkest night dusted with a wash of stars. Dark Matter is an intensely deep carbon-black cream eyeshadow that can be used alone, or layered with a cascade of our duochrome pressed pigments in six shimmery shades. A light that never goes out. Light Matter is a taupe cream eyeshadow that also functions as a shadow base for our pressed-pigment shadows, helping to adhere the otherworldly shimmer with no fallout, for a more-subtle effect. Tip: Swipe on the Dark Mat.
