For me, i have dark brown eyes too so i love wearing
Russian smoky olive
Russian smoky brown
Vivi ring brown
Symphony gray
French gold olive looks soo natural

I would recommend: double tint grey! They are super natural looking and brightening and I always get compliments - my friends say that they can't tell I'm wearing lenses since they look so natural :)

french shine gray is more like dark gray.
for green, you can check vivi ring olive :)

Hi sweet! For brown skin, to be honest, there are no rules at all!! But if you prefer dark grey colour or green colour, I highly recommend Double Tint, Vivi Ring, French Gold 3con

I would recommend you to check out the "Scandi collection". "Double tint" and "Eyelighter Glowy ash Grey" are very natural too.

Hello! since you have brown skin, bright colors will suits you!
Here's some of my suggestions:
1.) French Gold 3con Olive
2.) French Gold 3con Gray
3.) Smokey Gray
4.) Smokey Olive

Hope this helps!
