I think that the Obama example proves that color is about so much more than what technically flatters our skin tone. Certain colors make us feel good. (Some people say that you should wear pink and pastels if you want to give a friendly and approachable impression.) Others convey authority and power. (Obama has no chance of being elected in his geography professor outfit
) I've felt for a really long time that I have to balance what technically suits me and what I feel good in. (I feel powerful and in focus in black, but that helps me blend in too. If I want to stand out, I wear red. Soft whites make me stand out in a softer, more approachable way.)
I envy brunettes who can wear heathered gray as their basic neutral. It's so versatile, always work appropriate but great as a casual color too. (I have that gray on my 'official' palette too, but if I wear it, my mother asks whether I'm ill...) The learning curve to accept blues as my go-to basic neutral was pretty steep, I was not a huge fan but they definitely work in a way grays or browns never did.

I had a pair of widelegged brown polyester trousers circa 1996. It was a disastrous color and style for me but I can see you are ready for a revival...
Snowdown the classic trench coat color makes my hair look dirty and ages me by a couple of decades
The same for the classic camel coat. It took me a long time to figure that a lighter off white trench can be really flattering. For me, winter coat colors have always been tough. The best ones I have ever had are soft white, bright green, and pure black. I also have a 'swan' neck and polo necks are fantastic on me but long, slim scarves make me look sad and drawn. This winter was very easy because polo necks were everywhere and I could wear them instead of scarves.
Oh, and I just had a nightmarish feel what a HoC texture class could be like let's not go there. I saw a great example of texture at the supermarket today. A thirtysomething woman with two toddlers. She had long brown hair, dyed blonde with roots, a bit messy. A long slightly asymmetric black coat with leather sleeves but the rest of it was black shearling or synthetic. She had a black messenger bag made of very grained leather slung over her shoulder and wore pale gray straight leg jeans and black partially unlaced lace up boots. Very few colors, not busy at all, but she looked fantastic.
