Vaez - your images have an exposure and white balance problem.
A camera's light meter is fooled by the brightness of the snow and tends to underexpose it. Many cameras have an exposure compensation control and a good place to start is with setting it to +1. That is my usual starting point for winter images (we have snow from December through the end of March most years, so I get to do this a lot).
The blue tones are common when the camera's white balance has been set to an artificial light (tungsten) setting. Snow is white, not blue.
