The ball issue I am now really confused. So the balls in Clair are different then in the rainbow? Since rainbow is one color fits all? And the Voyager, is that one color fits all too? So what does a Pink Casper do???? The Voyager is more matte, the Clair is more glistening? Is that like sweat???? No what we don;t sweat, we glisten.
The balls in Clair are different than what will be in the rainbow, yes. They usually list what each ball "does" for your complexion, too. I would say it can be close to one color fits all, because they are so, so, transparent. I have the holiday balls from 2014, and while the majority of the balls are bronze, pinks, and red, it doesn't alter the color of my foundation or anything when I dust it on with a big fluffy brush.
I wouldn't say clair is glistening like a dewy look or sweat. I wear matte foundations, though, so it just livens them up after setting spray so they don't look as flat. I'm unsure how it looks over a very moisturizing/dewy foundation. I have never tried the voyager balls in person. So it's hard for me to say.
Here are some pictures of my balls (LOL!) and you can see the balls are all different colors... yet they still work on my complexion! HTH!
