I think I have my lens color sampler figured out. I used a ruby red on my first run. Didn't start off dark enough and discovered it is just too pink anyway, those are the slides pictured.
I pour a second run tonight using the scarlet red. This time starting with the intensity of the last slide and increasing 2 drops per slide instead of one. This is definitely the color. The residue I had left in my pitcher was a dead on match to the lens.
I kept precise records so I should be able to exactly match any lens.
