This website says that this dye is used in the leather industry.
I also found that it's in these paints(I know it's not very helpful).

So I have tried some chromatography. It is a mix. From left to right:
1. my first run - I used previously dissolved dye that was left in a glass after it dried out. I have addes some denatured ethanol and probably also
some water, do not remember exactly. This one has the most focused bands in the front.
2. Another run with denatured alcohol only. The bands in front are not so nice.
3. Water only. No visible separation at all.
4. Water alcohol mix. Nice separation but not so nicely focused as in the first run.

Looks like at least three- a blue, a yellow, and a green. You can separate the dyes by cutting the paper, and see if any of them respond to different
pH solutions.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.
