I'm Doing a Paper Chromatography lab and was wondering if all pens have single dyes, or multiples dyes?
From my lab results, there is just a dot with one color, but on a different pen mark, there are multiple colors.
MY answer would be that pens are made up of both single, and multiple dyes.

According to your results you are correct, pens contain single dyes and/or multiple dyes.
