I've had the same 5 MAC eyeshadows for about a year and decided I need to experiment with some colour a bit more. While I didn't get the chance to try colours out in the shop, I had a look online and looked for some swatches and one of the colours I picked was Coppering.
While initially it looked quite orange at first and I wasn't sure about it, after I played around with it a little and swatched it, I soon realised it was this beautiful burnt orange or copper! I wouldn't normally pick orange as an eyeshadow colour, but it's good to try something out of your comfort zone.
Anyway, Coppering has a veluxe pearl finish, like all other MAC eyeshadow the texture is very fine and it's great to work with. The pigmentation is good, but if you're looking for a really vibrant colour I would suggest using a primer just to make it pop all that more.
I've seen some people wear this colour on it's own, but personally I think it make me look like I had tired red eyes. I prefer to wear this with gold and just a hint of black/dark brown in the corners to give a nice "sunrise" look. Here is a picture of how I wore Coppering.
What's your favourite MAC colour?
