Colour of aliens

[GaviG]

Here’s a ridiculous question....and I bet it will get loads of abuse....This is hard for me to put into writing, If different colours of light are different frequency’s of light that we can see, and higher frequencies are ultra violet and microwaves that we can’t see. Maybe aliens look at earth, and all they see are ultra violet light and radio waves as their eyes have a different frequency response. They look at our plannet and think it’s all blurry and weird..... kind of what Jupiter looks like to us.... maybe when we look at Jupiter we’re actually seeing their WiFi network or something.

Even here on Earth, different animals see different ranges of colours. Birds and insects can see into the ultraviolet and, in some cases, infrared. Some flowers are much more "colourful" in the ultraviolet range in order to attract pollinators.

Humans have three colour receptors that, roughly, correspond to red, green and blue. Some animals have fewer (OK, we can understand that; they just don't see all the colours we see). Some birds have 4 colour receptors so they can see a range of colours that we can't even imagine.

It is entirely possible that aliens (if they exist!) would see colours very different from us. (It is unlikely, for various reasons that they could "see" radio waves, but perhaps not impossible). But they would not see the planet as "blurry" necessarily; but their view could be weird compared to ours.

The reason Jupiter looks "blurry and weird" is because all we see is clouds and complex weather patterns (and its a bit blurry because it is a long way away): https://www.universetoday.com/15132/weather-on-jupiter/
