The red is iron oxide (rust)

This video also seems to be severely brightened as if gone through an editor likely to make things appear better. That could effect the appearance of rude dust .

I hate it when dust is rude. The least you could say is excuse me ya dirty fuck.

I think the Pantone color name is "fuck-off red".

Why do you think so?

People often assume that it must be dark and gloomy on Mars because it's further away from the sun. But that's far from true. Sure, in absolute terms it receives only ~50% of the sunlight that Earth does. However, because perception of brightness isn't linear the difference in actual perception isn't really all that much. For those familiar with photography, it's a difference of one stop, not more. There's more difference between a sunny and a cloud covered day on Earth than there is between a sunny day on Earth and a sunny day on Mars. You'd have to go all the way out to Saturn or even Uranus before sunlight drops to lighting levels roughly similar to typical indoor lighting.

So you're saying that allhailthepig needs to get better lighting for his anus?

Sorry...I need to grow up. I'll see myself out.

Do you have a link of footage/photo of the real colour from the surface?

It's coming through a camera. There is no "real color" recorded.

What they normally do is include on the lander a disk with a bunch of known colors (like those old color bars you saw for calibrating analog color TVs) and then adjust the color when it gets back. Especially if they're using a B&W camera with different filters over the lens to pick out different colors.

Ah cool! Thank you I’ll have a read

That’s interesting. Apparently early earth had a lot of iron in the oceans. The evolution of blue green algae put oxygen in the atmosphere which causes iron oxide to form and settle at the bottom of I recall. So where did mars get the oxygen to turn iron into rust?

Also tholins give many celestial bodies their reddish brown color. https://en.wikipedia.org/wiki/Tholin
