In most cases these will be a single dye/pigment so will just make one coloured band on your paper. Black ink is a mixture of many dyes so would probably be this best choice.
Note that some inks which are permanent will not separate well using water for your solvent - in this case try a mixture of water and alcohol or an organic solvent like petrol+ethyl acetate.

I've been a science teacher and we used blue ink and black ink in paper chromatography experiments to demonstrate that both contained a mixture of different coloured pigments. I've never tried red or yellow ink, but my guess is that both only contain one coloured pigment, so the experiment wouldn't demonstrate anything interesting.

Paper chromatography could artwork to boot as common chromatography. except you're doing length exclusion chromatography the compounds separate in line with their polarity no longer their molecular weight.

can't get all the colors - it must be either RGB or CMY
