Fillets not fish

What ever you add will not be reactive with the epoxy since it is of a 
different chemistry, and even if it was the same, the stoichiometry would 
be messed up. As long as it is small amounts the properties would not be 
drastically altered, but the problem here is that the paint usually has 
alot of solvent in it, and that will be trapped in the fillet mix. Also, 
all epoxy resin will yellow with age, hence one of the major reasons why 
auto paints are not epoxy based.
The real answer is this. What you want out of this scenario is white 
fillets. Look on the Internet and call DuPont. You are now Jim's Custom 
Coatings Inc. Ask for a sample of R-900 Titanium Dioxide. In about 1 week 
you will get a 1 lb can of pure TiO2 for free. Add %-10% by weight to you 
resin and you will have the whitest fillets in your neighborhood. Do not 
change your epoxy mix ratio. This stuff is totally safe as it is THE white 
pigment used in all paint, make-up and toothpaste.

Question???
Can I mix PPG color with epoxy and microballoons for a colored fillet? The 
fuse is painted and the stab is covered and installed. Will there be a 
problem with the concoction curing or yellowing.

TIA
