Perhaps. I've never seen much of a color purity difference between shellac and red gum. However, shellac seems to burn better with Chlorate, and red gum with perchlorate. That may make enough of a difference. I use a similar formula containing chlorate and RG with a bit of charcoal, and love the color. Given the price and difficulty in obtaining shellac for me, I will be staying with red gum.
Older but still useful(?) formulae, especially blue

Very nice! I think nr. 2 and 3 are the best ones.
I just wonder how dangerous potassium chlorate is with sulfur? I see that it is still used even by some professionals, and of course I have tested it myself on a very small scale. Though it gives astonishing colours. The second best green composition I have ever seen was a composition with barium nitrate, potassium chlorate and sulfur. Only barium chlorate beats it.
