This portion of a tree in my backyard had lichen that fluoresced in three different colors!
This was taken with a UV390nm flashlight covered by a Wood's Glass filter to allow the UV wavelengths to pass through, but block visible light like the purple-blue light you get from most UV.
I also used a Yellow #2E filter on the camera to block direct UV and help eliminate the purple-blue further. The combination lets me capture only the fluorescence.
