There are two chemical classes, organic and Inorganic. They comprise all the compounds we know.

Organic Examples Organic Examples
Hydrocarbons - chains and rings petrol, benzene Salts NaOH, NaCl,ionic compounds,neutralization reaction of an acid and a base.
Steroids - Interlocking carbon rings Vitamin D,bile salts, cholesterol Minerals Silicates
FeO,Iron oxide
AlO, Aluminum oxides
CO, Carbon oxides
CO_3, Carbonates
C, Carbides
CN- Cyanides
Carbohydrates - sacharides glucose, sucrose, starch, cellulose
Proteins - Multi-Amino acid Phenylalanine, Tryptophan
Nucleic acids - Long nucleotide polymers DNA, RNA
Lipids - Hydrophobic H:0>2:1 Triglycerides

Salts that have specific colors in fireworks applications

Color Compound
Red strontium salts, lithium salts
lithium carbonate, Li2CO3 = red
strontium carbonate, SrCO3 = bright red
Orange calcium salts
calcium chloride, CaCl2
calcium sulfate, CaSO4·xH2O, where x = 0,2,3,5
Gold incandescence of iron (with carbon), charcoal, or lampblack
Yellow sodium compounds
sodium nitrate, NaNO3
cryolite, Na3AlF6
Electric White white-hot metal, such as magnesium or aluminum
barium oxide, BaO
Green barium compounds + chlorine producer
barium chloride, BaCl+ = bright green
Blue copper compounds + chlorine producer
copper acetoarsenite (Paris Green), Cu3As2O3Cu(C2H3O2)2 = blue
