I'm trying to (reasonably) match a color. I'm using some powdered

But...

Won't a series of twofold dilutions of small amounts get you where you want?

You only need to be able to measure one amount consistently each time,
if you start with two times the end volume in the first batch, then
remove exactly half that into an equal amount of diluent. Mix that and
remove exactly half to another equal amount of diluent (...and so on to
very dilute).

Then mark which one is the proper dilution, and you know it is a 2^n
dilution of the undiluted stock.
