my answer
Black absorbs more EM than white, but black objects also radiate more. All matter above 0 degrees K radiate EM known as "black body radiation". Black objects radiate that energy more quickly than white objects, so they get cold more quickly.
"During the day in a polar region", means that in the dead of winter it's dark out, even at noon. (The question didn't specify the season.) If the sun is below the horizon or very low in the sky (i.e., traveling through a lot of atmosphere), the solar EM wouldn't be much, in which case the black would radiate more energy than the white, and the inside would get colder.
Also, even if there is some sun, the surface of the coat is on the outside of the insulation, so any heat that it absorbs would quickly radiate back out into the air before that heat could penetrate the insulation to help warm you up.
I didn't look any of this up, it all from memory so I can't guarantee it's accuracy.
When spell-checkers came out, it was a godsend for me. If I left my spelling mistakes in my writing, you wouldn't be able to make out half of what I was saying, it's so bad.
A lot times I can't find the words in the dictionary because I can't spell it close enough to find it. I use Google a lot now because they have AI/phonetics algorhtms.
(I left that last word misspelled, just so you could see how I tried to spell it unassisted so you get a feel what I face with this issue. It's a real pain.)
@freemo @Pat Heh, and I usually turn off spellcheckers... because I absolutely hate the squigly red lines! They actually distract me!
I'm still trying to figure out where I can turn it off in outlook.office.com because it's English-oriented and my conversation language is Dutch.
I guess I'm teaching that stupid dictionary a lot of Dutch words now... :P
@trinsec I know everyword I am trying to say, and spell it perfectly. Its not my fault that the dictionary can't keep up with the latest spellings!

@trinsec
hahaha valid. Honestly if i could actually edit posts on here there would be a lot fewer of them. At least on matrix i will occasionally correct my mistakes. Here I see them but usually after i already posted and only once i reread it when going over replies.
