So in movies or art when creatures can see in different spectrums or when we view different spectums through digital technology it is either a nightvision style IR or a heavily modified reverse pallet like Predator.

This morning I thought of something new though. Being capable of seeing different parts of the spectrum likely interpret their lowest range as red and their highest range as violet, but they are just in different places. So like, where a human sees orange, a bee or whatever sees more yellow. This is also due to the TYPE of photoreceptors they have, but this post is more about the interpretation of what is seen than HOW it's perceived.

So if you modified a humans eyesight to have like, 30% more spectrum visibility, they would still interpret the colors they see as the usual ROYGBIV of the rainbow, but there would be a lot more subtle shades in between. So if you showed them something that looked like a normal rainbow to most people, they would experience it as a bunch of different shades of orange with maybe one yellow line at the beginning or a red line at the end.

Meanwhile they would be dressing in what they thought of as vivid reds or violets that we see experiencing as mostly whites and blacks.
