Colored Paint bbs for Airsoft Gun? - paint bbs sites

I have a gun, Airsoft gun, usually made of copper BBS not used. I've heard it called paint BBS BBS, where if you shoot the gun and the BB hits the target, because it will splash of color into it. Something like a paintball gun and less ammo. Has anyone heard of it? What are their names? Are they in shops?
Thanks
