Colorimetry at home?

Is there a reasonably priced option for colorimetry at home? Is this even a good option to accomplish my goal?


I'd like to roughly determine the concentration of a chemical in an ethanol extract from a natural product. It has a definite color. I would be able to buy small quantities of the purified product from a chemical supplier. Based on my recollections of college chemistry, I should be able to make a solution of known concentration and compare them with a colorimeter to determine how much I've extracted. Would this be reasonable, or should I be looking at another way of doing this?
