Is a planet with a primarily reddish/pinkish sky a plausible place for humans to live on?

Assuming that the sky isn't that color because of excess pollution, would the makeup of the atmosphere need to change?

And if it were breathable, would the necessary position and color of the sun cause unliveable or drastic temperatures on the planet's surface?

In other words, assuming a world of humans with slightly advanced technology, is this aesthetic choice of sky color scientifically sound?
