Factory Grey is probably my most loved grey/greige polish in my collection. It's a light heather grey creme. It's unique in my collection because it has no extra tones in it - it doesn't lean purple, or blue, or brown, or any of that. It's a grey that's JUST grey. I like that. I can see people being bored by that, but I love that about it. I've had this for about three years and I really cannot count how many times I've worn it. It's the color I go to when I'm not in my normal blue/purple/blurple/greige mood.
I chose Nicole By OPI's Follow Me On Glitter for my ring finger because I don't get too many chances to wear it. It's a glitter that sits in a dark silver/grey base, so it's a tad too much for my brighter colors, and I never usually put glitter on my vampy polishes, so I figured combining it with Factory Grey would be a great time to use it. Follow Me On Glitter is another color that's different from everything else I have.
