CES Article - high nitrogen pyrotechnics
http://pubs.acs.org/cen/coverstory/86/8626cover.html
An interesting article about typical pyrotechnic compositions, and especially potential new ones, which can be both brighter and less polluting. Less
polluting compositions are especially important for indoor fireworks, ClO4, Ba, and smoke in general being the main problems.
'High-nitrogen compounds' like bistetrazoleamine can be used with much less/no perchlorate, and they also generate much less smoke so less colorant is
needed. They are not cost competitive with the usual stuff, but that might not be so important for the small scale hobbyist! Is it practical to make
any of those 'high nitrogen compounds'?
Also some talk about using nitrocellulose, which doesn't need much ClO4 and with little smoke also can use less colorant.

Good find! I assume, though, that these will be even more easily regulated/restricted than nitrates and perchlorates...
