Want to squeeze the most from two chlorate star comps

[50AE]

I have something like a property in myself, like I think that something can be done better if tweaked

 

For example, I'd like to know if I can make slightly better colors with these two compositions.

 

Potassium chlorate 63

Strontium carbonate 21

Red gum 8

Shellac 3

Dextrin 5

 

It makes a good deep red, but it goes a little pink, not blood like red. Some say that shellac improves the red color. Should I try to replace the rest of the red gum with shellac ?

 

 

 

 

Potassium chlorate 66.5

Black copper oxide 13.4

Parlon 5.4

Red gum 9.9

Dextrin 4.8

 

 

It makes a very acceptable blue, but some say about the perchlorate version that if they substitute the red gum with hexamine, the color is better. Is it true ?
