I used to use Texture as a blush, but now I just use it on my eyes because mine is so old (it has a screw top) lol. I need to buy a new one, but I'm too cheap. It's perfectly fine to use any eye shadow as a blush.
I'm not a WOC but I have used Coppering, Sushi Flower, Passionate, and a few others as blushes. Sometimes it's easier to use it then to try and find a blush in the same colour family.
I have used Swish and Expensive Pink as blushes and they are pretty as can be.
Also have used Canton Candy Paint as a blush and it's frickin beautiful!
i do aaaall the time. i bought beauty sleep randomly and it works nicely as a blush. so does sushi flower if you use it lightly.. most any neutral/pink shadow will work great as a blush, especially if you want a little bit of a different texture on the cheeks. also for dramatic or theater makeup different color shadows work great. and on a side note, i use satin taupe to softly sketch in sideburns for myself on some days as it perfectly matches my haircolor.
