blue snow

White is not white unless it has a blue tinge. Did your Ma never put a blue dolly into the sheets washing ?

Or you could set a custom white balance using a grey card.
That would be a good plan, but if OP doesn't know why its blue, that sounds like a step too far, don't you think?

Not really its very easy to google
By pointing the camera at a white or gray card (angled so that it is reflecting light as a neutral reference, filling the screen completely with it, then pressing the White Balance button (or set it in the menu), the camera does its WB calculation.
From then on, any picture taken will have its colour temperature shifted appropriately. It's quite simple, really, and you should not be afraid to try it out and see your pictures improve considerably (assuming there is enough light for correct exposure).
[A "neutral" gray is 18% gray and will reflect all colors equally.]

None of which tells the OP why the snow appears blue.
What we 'see' is merely light reflecting off the various objects and surfaces around us.
The 'white' snow is reflecting light from the blue sky. Since 'white' is merely reflected light of equal proportion from the visible part of the electromagnetic spectrum (red, green and blue) any variation in the mixture of light hitting the snow will result in different hues being recorded.
Unless the snow is in direct sunlight which is 'warmer' in colour, the majority of light being reflected is either from blue (or grey) sky which will affect it's appearance in your images.
The human brain compensates for this - your camera doesn't.
That's why the snow appears blue. In ye olden days of filme we used 'warm-up' filters to compensate - now you can do it in photoshop.

If you actually look at the snow you will notice it does have a blue tinge in shade when the sky is blue. The camera is just recording what it sees. As said above our brain is compensating because it has been told from young that snow is white. But it's not always so.:nono: Look closely.
