Illamasqua Bacterium Nail Varnish ($14.00 for 0.5 fl. oz.) is described as an “opalescent beige” with a shimmer finish. It is a really intriguing shade, and I think those who tend to collect nail polishes may appreciate this shade in particular. It’s just weird–in a good way–it’s this cross of green, beige, and brown with threads of silver and iridescent opal. The base color reminds me most of khaki–brown with this murkiness–but the way the opal shimmers and reflects light adds interest to the shade.
