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.

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.

Thats ok, I'm usually crying when I post too, as well as any other time :)
