I know I'm probably behind the bandwagon a bit, but sorting through some earlier photos and trying to at least review or swatch most of my MAC blushes.
Dollymix is a brightened vibrant pink, it's not quite fuschia but a few tones brighter it would be a hot pink.
Here are the swatches, applied lightly and more heavily. On the skin it's a wash of slightly shimmery strawberry pink. Quite pretty. I do wish the consistency was a bit better, I'm not sure why but the surface of MAC blushes tend to go a bit funny or crumbly looking after a while (despite I always use a clean blush brush on any makeup).
Overall 3.5/5. I have to say it's not too exciting to be tracked down. Many drugstore brands nowadays would do a bright pink that easily duplicates this.
