Paint color/code

My daughter has a 2000 Cavalier it is Aqua.....I think.   It was the first year for that color.  I want to get some touch up paint for her door ding/chips. 
Does anyone know how I can get the color code so I can order from Chevy???
Thanks!

Dealer will know if you just show up and ask.  Vest to have VIN and or vehicle there. However...

You can find your paint code on the vehicle.  Here is a link to figure out which is the paint code.
