Oh don't they look Christmas-ish together. Scarab is a deep metallic red and appears a little darker on the nails than it does in the bottle, not that you can tell :-P
I don't actually have a lot of reds so this makes a wonderful new addition to my excessive nail polish collection :-D Flash shot above and I believe 2-3 coats although 2 would be plenty.
The winner for me is Viridian. I know I lean towards the teal/green/aqua colours naturally but this colour, in sunlight is drop dead gorgeous:
Viridian is described as a peacock green. Flash shot below:
I think this might be a new favourite! On a side note, there is some amazing artwork in the Illamasqua Autumn/Winter 2010 catalogue. Blown away!
