I think the technically more specific phrase to use here is ‘Bisexual Lighting’, which more specifically refers to scenes lit with a blue/purple and red/pink light, from roughly opposing angles.

Bread Tube is fairly notorious for significant use of ‘Bisexual Lighting’, blame Contrapoints, I think she either started or greatly popularized it first.

Evidently the term predates the term Bread Tube, I think?

Anyway… … now that I uh… ahem, examine this scene more carefully…

Are you actually using two different colored lights/lamps?

Or… a single, UV light/lamp?

I could be mistaken, but the way that light works on uh… exposed skin… reminds me of UV.
