I think I would prefer my students to hold up cards saying "Covalent" or "ionic" - this is hard enough for them without having to make the extra connection that red means "covalent". No point learning something you dont need !
If you must play the traffic light game then you could colour the words on the cards. its a good idea though to make a game out of it to get the whole class thinking rather than just sitting back.

Really useful thanks. Only points to note is that hydrogen is a covalently bonded element, and strong forces exist between individual atoms in both ionic and covalent substances (although technically ions in ionic compunds).
