This formula by Gary Smith make a nice Aqua star
in %
Barium Nitrate 40
Potassium Perchlorate 15
Parlon 15
Copper 2 Oxide 15
Magnalium 325 mesh 12
Red Gum 3
Bind with Acetone for cut stars or add an additional 5% dextrin and bind with water if you want to roll them. Prime with something like fencepost prime.

Never tried yellow stars but 'Forli Citron' is the only Mg/Al-fuelled lemon I can see on Passfire's database.
Barium Nitrate 9
Magnalium, granular, -325 mesh 4.2
Red Gum 1.5
Parlon 1.5
Cryolite 1
Gum Arabic 0.85
I've also heard good things about using Barium/Strontium to achieve a good yellow, ratios around 37.8 : 23.2 which might need tweaking. I'd be interested to hear if you find a good matched pair of formulas - aqua/lemon is a really nice combination.

I'm a big fan of pastel colors. I have a whole series of them worked out, but haven't gotten a chance to try them all in the air just yet. Pink and aqua is one of my favorite combinations actually. It pairs really nice with titanium inserts like tourbillions and farfalle. It's sort of a take on the red, white, and blue combo that is popular here in the US.
I do use optical colors for yellows and oranges now. Creepin_Pyro has the ratio written in an odd way, but that is about what I use. It's 55:35, which does only add to 90. It's approximately 61:39. This is green:red by the way. It's a beautiful, canary or lemon yellow. You can mix two different formulas in the ratios you want, but I find it easiest to use a red and green set of formulas that either have strontium and barium nitrate or strontium and barium carbonate used interchangeably such as ruby red and emerald green. Then you can just use the correct ratio of barium and strontium, and the rest of the formula is the same.
