I need information on ammonia and the addition of other chemicals to it and their reactions.

Example: Is there chemicals that can be added to ammonia to create a color?????????

You need to be a bit more specific. What kind of reactions are you looking for? Have you tried the Kirk - Otthmer Encyclopedia of chemical technology? You can find it in libraries, and that may help you.

I'm not sure what you mean by chemicals you can add to ammonia to get a colour? Certainly there reactions involving ammonia that produce dyestuffs/intermediates, an example being the ammonolysis of anthraquinone sulfonic acids (e.g. anthraquinone-1-sulfonic acid) to produce amino anthraquinones such as 1-aminoanthraquinone. This is an important dye intermediate. You get to this compound by catalytic oxidation of anthracene to anthraquinone, sulfonation of the anthraquinone using oleum to obtain the anthraquinone sulfonic acid, then ammonolysis. Alternatively, you can do a batchwise Freidel-Crafts reaction, which condensing benzene with phthalic anhydride in the presence of anhydrous aluminium chloride. This gives ortho-benzoylbenzoic acid, and you need to then close the ring by using concentrated sulfuric acid as a catalyst. This gives anthraquinone.

This is just an example, it may not be what you're looking for at all, hence why you need some specifics!
