: Re: Colours of ultraviolet I need to write something from the perspective of a character who sees colours differently from humans, and in particular can see multiple shades of ultraviolet. This isn't

It sounds like there is the potential for contrasting the experience of the species that can see UV and humans (or another species that sees a different spectrum).

We have a real-world example: some species of birds can see UV wavelengths. Two birds may look identical to a human, but are thought to look different when UV wavelengths are considered.

UVS vision can be useful for courtship. Birds that do not exhibit
sexual dichromatism in visible wavelengths are sometimes distinguished
by the presence of ultraviolet reflective patches on their feathers.

As another answer mentions, I wouldn't dwell on this as a major plot point. Still, it has world-building merit by adding "flavor" to the species, and could be the source of minor difficulties (or even amusing incidents) for a character.

"Different" vision doesn't have to only pertain to visible wavelengths. The magnetic compass orientation of birds may also be light-dependent.
