The key here is to use a spray enamel. There are newer spray paints that clean up with water...I'd avoid those; all the others should be fine.
The ones with a high VOC that flash off the carrier solvent in a couple minutes to allow a quick respray will be your best bet. If this is what it says on the directions on the side of the can, that will work well.
Surface prep for any painting project is a key endeavor; I actually sand the glass w/ a 600-grit (or finer) wet dry sandpaper, then use a good glass cleaner prior to taping and spraying.
Black or Navy Blue are great colors.
