Web black lights use these different materials so that most of the light emitted is ultraviolet (uv) light with just a bit of visible light in the wavelengths closest to the uv spectrum (indigo and violet). Under black light, certain colors will glow and appear brighter than others. Uv radiation has a shorter wavelength than visible light, which makes it invisible to the human eye.
