I was hoping to inform my friends and family of which chemical/element
is used to make which color in fireworks.

Are they diffrent from flame test results in anyway? Do they use
chlorides, nitrates, elemental form, or something else (or combination)
to make the colors?

I was hoping to compile a list:

Some of the common colors:

Red
White
Blue
Green
Yellow
Golden? (Orange-Yellow??)
Purple
Pink

Thanks!

Google is your friend.

About 6,580,000 hits for "fireworks colors." Not all are for
pyrotechnics. Take your pick.

I cross-posted to rec.pyrotechnics, they may have a faq available for
you. 'Tho I do know that the answer to your question is a lot more
complicated than you appear to think it is. For example, purple is a
little hard to create, the human eye's sensitivity in that range of
wavelengths is dropping off, so illuminated purple tend to wash out as
either white or red or blue. The salts used, likewise vary widely,
formuations are designed for a variety of purposes -- cost, stability,
burn rate, ease of extruding composition, to name a few. This is as
much art as science.

Back in my childhood, I read canonical books by Weingart, Lancaster and
Davis. Good luck finding those references these days.

Sir:

Weingart, Lancaster, and Davis are still available. They have been
complemented by others such as Hardt's "Pyrotechnics." The latter is
especially recommended.

On the internet, there are some freely available e-texts and reliable web
site (though plenty of unrliable ones as well). One of the better English
language sites is:
http://www.pyropage.com/

Sincerely,
JS
