I thought to be a Winter you'd need to have very cool and ashy tones, but Deep Winter is actually both warm and cool tones; I'm back to uncertain between deep winter and deep autumn :) a few colors that overlap? Black, Chinese Blue, and Emerald Green
People categorised as Deep Winter are naturally dark, with a slightly cool tone to their coloring. There is plenty of contrast, but not as much as the other Winter seasons. Black is excellent on them, making eyes really shine bright.
