    unless their sun was the same temperature as Sol and their planet the same size as earth

    Most other animals see different colors than we do, and they live under a star of the same temperature as ours, and in a planet with the exact same atmospheric composition.

      The sun is the big one. What we call “visible light” is just the band of the em spectrum right around Sol’s peak. A larger\hotter star would have that band shifted dramatically bluer, while a smaller/colder star would be redder.
