Temporary, the surface illumination is really red, caused by dust-storms, darkening the sky. The image on the left was taken shortly after or during such a storm and the diffuse light with almost no shadows is visible. In contrast to this, the image on the right, shows sharp shadows and clear blue sky, the normal condition on Mars.
On the image-data of the Viking- and Pathfinder-Missions, this diffuse illumination is a very rare condition and not the normal state, as NASA seems to publish it with their dull-red picture

. "The organisms live between the surface of Mars and a thick ice cover that isolates them extremely well from Martian temperatures of around -120°C," said Ganti. "When the spring comes and light penetrates the ice, these organisms absorb the energy of light and warm up themselves. Under the ice, temperatures rise to slightly above 0°C. A thin inner layer of the ice melts, thus creating the conditions of life. In the summer, when the whole ice cover melts and the water evaporates, they dry out again," he said. The dark spots start spreading in the spring, varying from 10 meters to several hundred metres in diameter. "The organisms could be algae or lichen at the most, similar to organisms that can be found on tundra close to the earth's North and South Poles,"

What is more than interesting is 'red' sky - but that was not the case back in '76 as we can see from Viking images - original data no corection!!!

That place is just too damned cold and dry to sustain any larger lifeforms.

My guess is that a lot of the stuff people see as "vegetation" is a result of darker, windblown material settling in crevasses, or possibly left over from melting ice. Anyone from a part of the world where the snow melts in the Spring and leaves little piles of dirt in the street knows the process I'm talking about.
A lot of the misperception about the Mars stuff is the way it has "branches" or "veins." Yeah, trees and bushes and other forms of plant life do that, but there are also plenty of erosion processes that will give you that same shape. And folks are also fooled by the light and shadows of the photos

Some real pretty images, I love the one with the rocks and ground covered with white "snow" the most

LOL NASA uses red shift, Keith uses Blue shift ( as evident again by the blue color on the corner that shows a piece of the rover... So we will never see an "unshifted" image it seems
