Do anybody know what colour does semen stains glow under a black light (uv light)?
Blue or Yellow?
Would it affected by the wavelength of the black light?
How about a 300-400nm(wavelength) black light?

Thanks.

The wavelength will only affect intensity of fluorescence.

No clue, but if you have a light, it should not be hard to test.
