This is real deal, very bright and brilliant synthetic fluorescent yellow. Daylight fluorescent pigments have a bright, glowing appearance. Their vividness can be increased by applications over a white ground.  Ours makes a gorgeous fluorescent orange mixed with our fluorescent pink, and a fluorescent green mixed with our fluorescent blue. (see pics.) Standard 1/2 pan fits our enamel travel tins.

Chemical description: Triazine-toluene sulfonamide-paraformaldehyde polycondensation resin with synthetic coloring matter.
