So the pictures have numbers for each cokor, but the labels/bottle only have names...so if I wanted #3, which one is that?

Beige. If you look at the arms with the numbers on them, and then go look when choosing a color by name, you just count forward as you swipe through color choices.

Does this have parabens?

Theres a long list of ingredients, but the word "parabens" isn't among them..If you mean stuff like magnesium sulfate, dimethicone,silica, etc. then maybe those could be parabens (I dont know what that is)
