Why....is the sky...blue?

Mars has a shit load of carbon dioxide up its atmosphere's ass. Much more than nitrogen (which gives our sky a blue color.)However, perhaps nitrogen gives off a dominant coloration or some shit. Who knows

This is an absorption spectrum. It starts to arise around infrared, so it shouldn't give off a visible color of any sort besides a hint of red at most (which it shouldn't). Even then, it would probably just be dust. Spoiler

SpoilerYes, but the more dominant factor in determining the colour of an atmosphere is emission spectrum, and you'll note here that the oxygen spectrum contain's generous amounts of blue, while the carbon spectrum contains more yellow, while still retaining some blue.Neither has very much red in it.That's why it's bluer towards the higher regions and turns a sandy colour closer to the horizon.

I'm liking that colour corrected image, looks sort like some generic desert in America.Still, that blue is dodgy- ignoring the CO2 rich atmosphere (as many have already mentioned would change the colour), the atmosphere is ridiculously thin, meaning there's not even much to create a coloured a sky in the first place. You can sorta see it on the top of the picture, with it getting darker during a Mars' "day" with stars visible.
We need to start terraforming now. Like right now.

We both know NASA has some sort of super secret plan that they've already put into action so that they are already centuries ahead in the process of terraforming Mars. They'll announce it one day out of nowhere sp that we all might see the human migration to Mars within our lifetime.Spoiler*sobs in corner*
Well let me tell you, acid is good for meat, and breaks down connective tissue, fats, and tenderizes it. Run the pH the other way and it turns into soap and you might as well bite into a urinal cake.Venus is not for the timid, or people too afraid to shove a fat bird out the airlock and let the harsh laws of thermodynamics do the work. Venus is for men. Men who like to eat meat – cooked in fire and acid and seasoned with the Devil’s own mix of volatiles boiled up from the pits of hell.If the thought of Thanksgiving Dinner on Venus gives you the heebie jeebies, you don’t even need to think about plunging into the roiling atmosphere with nothing but a cheap plastic heat shield and a thin balloon to save you from the crematorium that yawns down below. So man up, dangle the bird into the depths of the Stygian hell, feast as someone who walks between worlds and lives on an airship that rides the hell born winds 30 miles above a surface so hot it glows visibly red.
The color of the Martian surface.
