Features are individually distinct without one dramatically dominating the others.
Contrast level is a description of a visual relationship, not a ranking — no contrast level is presented here as more attractive or more correct than another.
Contrast level varies enormously between individuals within any broad group — hair colour, eye colour and skin tone combine in many different ways, and no demographic shares one uniform contrast pattern.
A genuinely wide range of colour combinations tend to feel balanced.
Jewellery and eyewear can shift the overall feel warmer, cooler, softer or bolder with relatively little risk.
Flexible — both soft and confident palettes commonly work.
Medium contrast means the features are clearly separated in lightness without one dominating: perhaps mid-brown hair with light skin, or dark hair with mid-deep skin and brown eyes. Visual attention goes to edges in proportion to the lightness step across them, so moderate steps give definition without a single strong line. Because the face already contains a range of moderate steps, garments can add contrast or reduce it without either choice looking out of scale — the reason medium contrast is often described as flexible. The level is still a description of gaps on the lightness scale, not a verdict on the colours involved.
How to check: In a greyscale daylight photo, hair and skin should read as distinctly different greys, but neither near black against near white.
