@mc well white and black are similar to albedo. White obviously reflects incident light and black absorbs it. If you want the answer I can DM it to you so as not to ruin the vote.
@freemo Oh! Okay. I'll delete my comment.
@mc your comment is fine (though answers are best CW'ed is all). I just know the actual answer so if i reply id DM it so i dont give away the answer and prevent discussion.
@freemo I want to say black because it absorbs light but polar bears are white and they seem like they know what they're doing.
@valleyforge Polar bears are actually way more complex than it appears. Their skin is black and their fur is white. Their fur acts like little fiber optic cables that channel light from the outside down to their skin where they warm up. It is actually quite brilliant design on the part of god/evolution/zeus.
@valleyforge Polar bear's skin attached.
But yea the polar bears black/white combo might actually be a clue for you if you think it through.
facetious answer
White clothes are better camouflage in a snowy environment. Getting killed by a polar bear would cause your body temperature to drop to ambient; thus white clothes are an advantage for staying warm.
@freemo @valleyforge polar bears: it was our idea.
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.
my answer
I use your by default mostly because I type to fast and dont review what I write. Couple that with the fact that i got into the habit by typing on my phone where an apostrophe is a bit tedious. That particular error, as most of my errors, are largely due to not caring and typing as fast as I can since i dont find the medium to be critical for correctness.
My formal writeups, as well as my blogs, tend to have very few errors since I proof read them.
That said my natural rate of errors has been unusually high the last 2 years since my injury and COVID largely due to the extremely high levels of stress I've been under which seems to effect the prevelance.
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!
@freemo Probably black clothes, but it depends essentially on the albedo of the material they are made off.
