Yellow in a picture
It was snowing last night and I went outside and took the picture below, which is totally untouched up other than the size. Please don't worry about the focus, etc as it was handheld and dark. My question is this, where did the yellow tinge come from. What I was looking at was white snow. Do you think there's some reaction between the sensor in my camera and that street light? This has happened before and I've wondered about it and how you correct it. Any thoughts?

I got the same. It seems street lamps have a very warm light. Some around are so yellow that I can't even correct it.
The human mind corrects it because it knows that snow is supposed to be white.

I'm no exactly sure what that means, but I'll take it as a compliment and say thanks..
EO "The human mind corrects it because it knows that snow is supposed to be white."
So are you suggesting that the camera (sensor) is actually getting it right, aka with the yellow? It's just our brain that is thinking that it should be white and therefore it is.
I hate it when that happens. :-)
Yep.
@ Tommy -
The yellow is coming from the street light, which is probably using a mercury-vapor or sodium-vapor bulb that shows as a yellow light in film or digital camera shots.
As Eolake says, our eyes tend to correct for that, but our cameras can't do that - they just tell it like it is, and it's a yellowish light.

Noooooo! No...I just can't accept that! So...snow is even WORSE than I thought?! We're even being fed LIES by our MINDS?! It's not that "crisp" WHITE that we have ALL been lead to believe for YEARS in magazines, films, and, shit...even whilst playing/skiing/digging out a damn car in it?! That's RIDICULOUS! What a damn...SHAM!! That has got to be one of the BEST kept secrets that I have ever heard! Can't even trust our own brains! Shoot! I'm lodging a COMPLAINT ASAP!
Life is such a CRUEL JOKE! :-(
(actually, I do know that our mind "plays tricks" on us; I just hadn't heard of this one! VERY INTERESTING, Eo!)
(Tommy: sounds like you've got an 'Admirer' in Anon! LUCKY DUDE! :-D
Shoot, yeah, happens all the time. Painters have to learn this. For example, a shadow in sunshine is not just darker, it's bluish because it's lit by the blue sky.
And the sun seems yellowish to us because it contrasted by the blue sky.
Interesting, Eo.
What color is white?...White is not a color...It's the lack of color...Snow is not white...check it out...snow is crystals which reflect the light shone on them...A white pigment (such as house paint)is just that...a white pigment...but shine any colored light on it and its not white anymore...
Quite so, white is an even mix of all the wavelengths.
And I think white pigment is actually little metallic particles just reflecting max light back.
We sure are getting technical here :-)
But, if I remember right..black is the absence of all color and white is the combination of all colors.
So Ron, are you suggesting that if I put a pile of snow in a room lit by a red lamp (only), that the snow would appear to be red?
Of course the foot or so that is sitting in my front yard right now, looks pretty white to me :-)
