In Ives' patent 1,121,187 he recommends the following dye baths:

Bayer's alizarin blue A S, 1 gram to 1 quart of water, with 1 gram of citric acid and 1 to 3 grams of citrate of potash. For magenta pink, equal parts of Bayer's alizarin rubinol R and rubinol 3 G, with 1 gram of citric acid and 1 to 3 grams of citrate of potash. For yellow, Bayer's sulphon yellow R, with 1 gram of citric acid and 1 to 3 grams of citrate of potash.

These dyes are cyan: CI Acid Blue 47, magenta: CI Acid Red 80 & CI Acid Red 82, yellow: CI Acid Yellow 42.

Although these dyes are probably not ideal in their hues, it will be interesting (if I can find them) to see what results Ives enjoyed.
