i fondly remember the asra fireworks `floodlights` in red/green and have played with various compositions in an attempt to recreate these,,the problem is a few grams isnt very effective, you really need 20g+ to get the desired effect and this produces a prohibitive amount of smoke..some time ago i bought 200g of hexamine when oliver brown was selling it and i wondered if i could substitute this for red gum in an attempt to reduce the smoke..i searched the threads here and on apc and done a bit of googling and learned that hexamine/chlorate is a nono so the vivid colours are out but i havent been able to find out if kcl04,ba/sr(no3)2 compositions would be safe,i can put up with pink reds and washed out greens if i can enjoy these in my garden without annoying the neighbours or attracting attention to my `activities`....cheers guys

Try researching compositions for low smoke lances.

thanks for the advice arthur,,,i found some ap based star comps that were hexamine fuelled so im going to give it a go with kcl04

They're low smoke because they use AP.  AP decomposes into all gaseous products, aka low smoke.  Using KClO4 will defeat the purpose.  Basically anything low smoke is made from AP or nitrocellulose.
