Mordant is a brownish plum. Very lovely.
Suffocation is a bright pink with a blue shift to it. It is apparently the eye shadow sister to Lost Kiss and very like Urban Decay's Omen except with a pink base instead of lavender. Like magic.
Valkyries is a pale petal pink which I am very happy to add to my collection.
Here's a look using Cerberus, Suffocation and Valkyries.
And here's a look using Mordant, Drakon and Suffocation.
Hell Froze Over is a sheer white. It kinda makes you look like you have frost bite almost.
