I remember on the old site we had a post about how to change the smoke color in the KNO3 and sugar recipe. does anyone have that old post or can they remember the other ingridients for all the colors?

uhh yeah i think you should look at colord flames

The thing is, the chemicals used to make the smoke a different color are extremely expensive and mildy hard to obtain and it's better to stick with good ol' kno3/su.

look in a chemisty book it has it listed in it waht elements will cause what color smoke

it has the chemical/color table in one of the versions of the anarchist cookbook
