There are species on Earth that can’t see certain colours like humans. For instance, dogs can’t see most colours like reds and greens and deer can’t see oranges and blues well either. But humans have a cap range of the different volumes of colours we can see.
Humans can only see within the visual range. Any colour above or below the range is invisible to the human eye. Human can see anything in the range of infrared light or ultraviolet light. These types of colours made within these ranges remain invisible unless technology is used to see the effects. In photography, there are lens that can pick up some infrared light. Different bulbs are used to make ultraviolet light visible.
There are animals that can see a wider range of colours like peacock mantis shrimp. They have the most complex eye structure in the animal kingdom. They are mounted on the face of shrimp on mobile stocks that can move independently from each other. They also have a complex visual system ever discovered. They have 12 to 16 photoreceptors in their eyes. This is in comparsion to the human eye that have only three photoreceptors. Their eye sight works like satellites.
Some future technology is based on this stomatopod.
