Mac Crew High-Light Powder is a mix of pale pink, lilac and apricot with a cream overlay. It's a satin matte finish which is quite unusual for a highlighter so if you're looking for something shimmery like a Bobbi Brown Shimmerbrick this is not for you. I also find that on my pale-medium skin this is far too pink to act as a highlight- it's much more of a pink blush on me. If you mix all the shades together (it's hard to pick up all the shades individually) you get a pale pink- a bit like Pink Swoon.
I used this as a blush and it lasted a good 8 hours before the edges started to fade. It's quite a dusty sort of powder so if you have dark skin it's best to try it out before you buy as it could potentially look a little chalky. Overall it's a nice product, not the most unique but I do like the new packaging. Temptalia kindly scraped off the top layer of beige and revealed that it doesn't go all the way through so with time it will come out as a darker pink.
