water based paints

i recently ran into a local artist who i am going to get a board painted by. i have heard that i have to stick to water based paints but does any body have any suggestions of type, color (ive heard stay away from red), or anything else

you just have to be carefull with yellow and red because they tend to run a bit. just test them on a piece of excess foam. i use water based paint that i buy from michaels. they have the stuff that they sell on foamez.
