Top picture is without flash, and is more true to colour, bottom is with flash in order to show the shimmer in the shades. A friend from the US bought these duos for me in exchange for items she couldn't get there.
Brousse is a bark brown and a smoky mauve combination; both shades are shimmery. This is lovely, and very wearable. Eurydice is a cool bright purple with violet shimmer and a deep charcoal with multi-coloured shimmer. It does look a bit scary in the pan, but I think this might be my favourite item from the Holiday collection (which is another great collection; I'm also tempted by the Aigle Noir eye colour pencil and by the Pop Life lip pencil.)
Here's a couple of pictures of me wearing Eurydice over Lili Marlene cream eyeshadow (grey.) It's dramatic, but I think the combination works really well. I applied the charcoal all over the mobile lid and quite high (for me) in my crease, and then smudged the purple shade over the mobile lid. I kept the rest of the face simple; a bit of lipgloss in Gothika (a sheer berry) and Illamasqua Primal blush (a beige shade) to contour instead of a more colourful blush.
