Why don’t highlighter colors exist on anything digital?
Highlighter colors are a type of [blacklight-reactive ink](_URL_0_). They reflect light like normal, but they *also* absorb ultraviolet light and re-remit it at a visible wavelength. That means that the ink appears brighter than it should given the level of ambient light, making it look like it's…
The Short Answer
Highlighter colors are a type of [blacklight-reactive ink](_URL_0_). They reflect light like normal, but they *also* absorb ultraviolet light and re-remit it at a visible wavelength. That means that the ink appears brighter than it should given the level of ambient light, making it look like it's glowing. Computer monitors are already glowing, so you can't really have this type of phenomenon with a lit screen.
