MAC Joy To is a moderately warm-toned, medium purple with a glitter finish. It is a limited edition eyeshadow that retails for $21.00 and contains 0.05 oz.
MAC Joy To Shiny Pretty Shadow ($21.00 for 0.05 oz.) has a rosy, brown base that flashed blue-to-purple most of the time; it looked like a grayish purple when I applied it to my lid, though there was a warmer base that came through at certain angles. It was packed with glitter particles and had a slightly sandy consistency, but it was sandy in the least awful way--I could tell there was a ton of glitter in the eyeshadow, but it didn't feel gritty or chunky.
If you know me, I'm not a fan of using my fingertips for application as I can't get much precision that way, though I certainly tried these that way but found that using a flat, synthetic brush (like MAC's 242S) worked just as well as fingertips and gave me the precision I wanted to cram three of these shades on my lid. I pressed and patted the product onto my lid, which had minimal fallout during application, but when I went to blend the edgse a bit, there was a little more fallout and some sparkles traveled.
It creased faintly after six hours of wear, though it didn't progress much beyond a faint line running my deeper crease area, with light to moderate fallout; after 10 hours, there was additional fallout but it looked like about 75-80% of the glitter was on my lid as the look had plenty of sparkle and impact at the end of the day.
