I think my dupe matches the picture you see on the Lime Crime website but not the colour in real life. I'll show you a side by side.
I used 2 big drops of Feathered with a drop of Tarred to get the grey base and added a tiny bit of Katricia for the purple tinge.
Here's my result
^^^Lime Crime's site swatch ^^^
No flash again
Here they are side by side in real life:
So side by side they look completely different but this was still fun to do. I think my version matches the site picture better however my skintone doesn't go with such a light colour so I'm kind of glad Chinchilla is darker in real life. It suits me better.
I think I can make my dupe match if I added a bit more grey but I'm going to leave it for now.
