Even if it's just sparkles by itself, it's just white, or transparent. One sparkle by itself is just transparent, but when it's grouped up together, it turns white, which is also a color. A pretty accurate reason if you ask me. I find it a little bit childish of arguing about sparkles. I mean it just has that "kindergarten" feeling, you know what I mean?
Anyways, I know that this weekend is going to be a normal one. I hope you readers have a good weekend, and have fun!
