If you found yourself on an alien planet which resides in the solar system of a sun with significantly bluer light than our own “yellow” sun, then everything would appear sot be in various shades of blue or colors heavily tinted towards the blue range of the spectrum. However the natives of this planet would see a very broad spectrum of colors as they’d be evolutionarily adapted to take full advantage of the spectrum available to them. I bet there are spiders on our own planet that can see more shades of blue than we can imagine. Maybe I’m just talking about humans that would be born on that planet. In any case Darwin was an evolved being, whereas those of us who claim to be Intelligently Designed are neither.
