Yes I am but when you actually put the different glass in  and the color
error gets worse, you try it the other way and see what happens.
Actually, I'd suspect that making the lenses doublets is what is needed to
get the job done and if you do cemented doublets, then the light reduction
will be minimally more than with the singlet lenses.
