Many are simple silicates. Some are compounding silica, metallic ( or non) and formers and modifiers as well and that's where the makers get really cagey. Zinc and potassium are really conducive to making reds. The blues are actually really easy fall off the log colorants. The issue is keeping the toxin level down in the secondary stacks and that's where they get way cagier still. Ferro does not want to talk. None of the others do either.
