Green Vaseline Glass on Blue Plate

This green vaseline glass has beautiful bright green fluorescences. The goal of this painting was to make them pop. I couldn't lighten these areas without losing the chroma, so I did it by darkening the surrounding areas.

Here's some interesting info on vaseline glass:
"The normal colour of uranium glass ranges from yellow to green depending on the oxidation state and concentration of the metal ions, although this may be altered by the addition of other elements as glass colorants. Uranium glass also fluoresces bright green under ultraviolet light and can register above background radiation on a sufficiently sensitive Geiger counter, although most pieces of uranium glass are considered to be harmless and only negligibly radioactive.[3]" Wikipedia.
