Viking 1975 mission had same color problems as this mars mission

"If you ask a Meteorologist about the reason for blue sky on Earth, he will name the Rayleigh scattering.
If you ask a NASA Scientist about the reason for red sky on Mars, he will name the fine dust in the Atmosphere which scatters light like during sunset on Earth.
But there are not always dust-storms on Mars which pollutes the Atmosphere.

So there have to be also days which show blue sky!
Even NASA / JPL writes in this article about the possibility of blue sky and 3 days before Pathfinder landed, this note appeared in a press release by NASA:

"If dust diffuses to the landing site, the sky could turn out to be pink like that seen by Viking," says Philip James of the University of Toledo. "Otherwise, Pathfinder will likely show blue sky with bright clouds."

And the pictures of this clear blue sky do exist! Especially from the Viking Mission, as you can see on the next page"

About the sun dail business, it's been done before:

"This is the color calibration table on Pathfinder.
It's a simple sun-dial with some color spots on it.
click on the images to enlarge NASA said, that they will sent the first sundial to Mars with the Mars 2001 Mission. This is wrong, as you can easily see that there is already a sundial fixed to Pathfinder!"

And.. last but not least, they changed the pics on the Viking as well:

Hot momma!

Holy... that is incredible interesting.
So it could be there was something that crawled onto the airbag, and the sky might be blue instead of red as the Nasa wants to make us believe...

The sky on Mars is sort of a butterscotch/rust color. The sky on Earth is blue because gas molecules scatter blue sunlight better than red sunlight, so the blue light fills the sky. On Mars, there is much less of an atmosphere�the surface pressure is less than 1% of Earth�s. So, the sky would be a very dark blue, with stars shining, if the atmosphere were clear. So far, though, every Mars landing has found a dusty atmosphere. The dust may be some sort of a clay-like mineral, but the color is because it contains small amounts of oxidized iron. And oxidized iron is a fancy way of saying rust. We know Mars has global and regional dust storms, but even away from the dust storms there are dust devils that throw dust into the sky. So, away from a dust storm, there is not a lot of dust in the sky, but there seems to be enough to keep the sky a bright rusty color.

An interesting thing about the sky�s appearance is related to the sunset. On Earth, sunsets are red and orange because all of the blue light has been scattered away from the Sun into the sky. On Mars, all colors are scattered away, but a lot of the blue light is absorbed by the dust (making the sky yellowish-red). The blue light that is scattered stays close to the Sun, and the result is a blue sunset in a rusty sky, instead of Earth�s rusty sunset in a blue sky.

Sounds like a very good explanation to me.
