I'm working on a Chromatography Lab and need to identify the pigments that appear on the paper. I've found the names of the green and yellow pigments, but I can't identify a brownish streak that appeared when a paper consisting carnation pigement was placed in water. Help please!

Brown? Are you certain it is not "burnt umber"? Burnt umber is in fact dark yellow.
