I confess that I'm not an expert on making paints, but I can look it up. I imagine it has to do with a couple of simple compounds, finding the right dyes, and generally just making sure you've got color, permanence, and adhesion to the mix...

Interesting reading I've set up for myself, really... Would you care to learn about that too? I can put the books you'd need on the pad I gave you and Takane... I suspect you're not the only one who'd appreciate the availability of paints.
