|Strong Orange with increasing amounts of Deep Navy|
With a weaker concentration of dye, the warm brown would translate into a sand beige, and the charcoal would become a neutral grey.
I learned from Anne Johnston that all commercially available dyes are either pure pigments, or a blend of pure pigments. She recommends that dyers acquire these 14 pure pigments and become familiar with the way they behave. So I chose pure pigments for this trial. Another time I might try the same experiment with Strong Orange and Mixing Blue.
Diane Franklin's Dyeing Alchemy referred me to a page on the Jacquard website, which gives recipes that use 11 basic pigments to create 71 mixed colours. I was immediately drawn to the recipe for chartreuse, which I have always found to be an interesting colour. The Jacquard chart recommends 64 parts Lemon Yellow mixed with 1 part Medium Blue. Isn't it surprising how such a tiny amount of dark dye can change the character of a light colour? (Jacquard's Lemon Yellow is the equivalent of Pro-Chem Sun Yellow and their Medium Blue matches Pro-Chem's Basic Blue.)
I found the result was a little "brighter" and "happier" than I wanted, so I tried again, substituting black dye for the Basic Blue, which gave a more "interesting" mix. You can see the two results below.
