I've done fabric dyeing using similar base colors but I'm sure the
pigments are different. *In my color samples, I have a nice reddish
brown that uses 1 part yellow, 7 parts cyan and 12 parts magenta.

With ink, I'd start with a few drops of yellow, add magenta a drop at a
time to get a medium orange, and then try adding the cyan. *Count drops
for each and then multiply.

This is the best suggestion, I'll try it using / counting drops. *I'll
mix in some real black if it looks too bad. *I just hatre to throw
away half-full bottles of colored ink that I won't use because I
bought too much as part of a package.

Don't worry. Hang on to it. It wll come in eventually.
