Rock sample in UV Fluorescence: Leopard skin rhyolite

I have been photographing rock samples under Ultra Violet light to see how they fluoresce. In this post I am looking at a small sample of leopard skin rhyolite. I am showing first the daylight and UV versions in a comparison slider:

leopard skin rhyolite in UV fluorescence on the same black shiny background

I find there are interesting colour differences when blended using different methods. I am showing two at a time in the comparison slider:

leopard skin rhyolite blend method 1
leopard skin rhyolite blend method 2

leopard skin rhyolite blend method 3
leopard skin rhyolite blend method 4

I am fascinated by the way different blends emphasises different colours.
