non-expert comments from someone who played with pyro as a kid, many moons ago:
the KCl should be pale violet but it appears overwhelmed by something orange (like glowing carbon from alcohol, or residual sodium?)
What should Pb be doing?
The Ba is not nearly as green as the mixes I made as a kid. Probably need an oxidizer to burn hotter.
The Cu needs a chlorine donor to get it nice and blue - very hard to do. Blue is an art form.
The Boron is a nice green. Apparently Boron is the new , cleaner Barium
Can't suppress Na yellow no matter what. That will mess up anything else in small concentrations.
The Strontium might be suffering from low temperatures or contamination, like the Ba - I recall a much richer magenta-red.
nice brick red from the Li - never managed to get that one as a kid - probably works at a lower temperature than the ones that failed (Ba, Sr, Cu) so you don't need a hot flame with an oxidizer.
