Do you mean pastel colors?
Yes and no. From Wikipedia:
"Pastels or pastel colors are the family of colors which, when described in the HSV color space, have high value and low to intermediate saturation"
When Wikipedia writes "high value" I guess they mean "high brightness". I don't necessarily want a bright skin. I was more concerned about the color saturation ("the amount of color in the color" for lack of a better expression).
I don't mind pastel colors, but I didn't want to use that word, because then people assume bright colors. I just wanted less saturated colors.
That being said I don't think I'm going to use a flat skin anyway. The reason I left a comment is because those colors reminded me of MS Metro colors which I also found too saturated. So it was my anger against saturated colors that came out...
