What is different between topCoat or basecoat with shine nail polish? howmany color is there for base or top?

The base coat is usually a clear nail polish that most brands say will either hold the colored polish better or won't let the colored polish stain your nail. I've seen a few base coat polishes that have a pinkish tint that actually looks great if you want a natural nail color. A top coat nail polish is always clear and sometimes it's a speedy drying polish, and it's considered ';chip resistant'; which helps your colored nail polish last longer.What is different between topCoat or basecoat with shine nail polish? howmany color is there for base or top?
