Late to a great thread!
I function at the medium level, I think, but I have high leanings. I feel a bit "held back" at the moment. Firstly, finances demand that I have a cohesive closet on a budget. Limiting the number of colors just make sense. Also, I fear looking less "sophisticated" in high contrast - high color outfits. If I were in Paris, being bright might feel like a brave style-setting choice. In the midwest, it feels a bit like you're channeling the lady in the Christmas sweater! On the other hand, if I let loose and allowed more color mixing, would I like the results more?
Right now, I'm avoiding the issue entirely, focusing on mixing neutrals instead. I actually wore dark brown booties, burgundy pants, my Loft print top and my charcoal tweed Loft moto. All at once. Mixing brown, grey, and print. I loved it! The brown simply bookended my hair and was lower contrast to my trousers than black would have been. I also added deep olive trousers for an earthy, interesting color to ground my cobalt and burgundy, and to break up my grey and black. These trousers will figure in my Post-Christmas-Winter-Wonderland capsule!
