This image is illuminated entirely by the UV LED of the MiX-7. Yes, it looks exactly like this in real life!
Just in case you want to see it with regular light instead (and without the ZWB2 filter):
Seven levels of brightness for the white channel, two for R/G/B/UV. Only one color at a time. Next to the RGB disco mode there's also a red SOS, a read beacon and a white strobe.
