You've heard it before: it's the effect of color on your skin that ultimately matters. Your eyes and hair are along for the ride.
Colors that seem to "go with" your hair aren't doing you any good if that hair is framing dirty-looking or shadowed skin. Colors that seem to make your eyes pop aren't helping if those eyes are popping out of a washed-out face.
Why is the skin appearance of prime importance?
Because when we look at other people, we use skin appearance - not hair or eye appearance - as our primary way of evaluating health. And health = beauty.
The human animal seeks to maintain life and avoid death. To the human animal, health reads as beautiful because health is life.
When you look at other people, you instantly and unconsciously evaluate their health, and you do it in large part using the appearance of their skin. If the skin looks right, the rest seems right too.
Healthy looking skin = life = beauty.
And when we judge the health of another's skin, I think the most salient feature to that judgment is its color.
Think about all the ways we use the language of color to describe the appearance of ill health in the skin.
We speak of
the yellow of jaundiced skin;
the green of nauseated skin;
the blue of frozen or oxygen-deprived skin;
the purple of bruised skin;
the red of burned or abraded skin;
the white of bloodless skin;
the grey of dead skin.
The fact that there are so many ways that skin can look wrongly colored shows that skin color is crucial to our estimations of others' health - and, therefore, of their beauty.
But color is not objective.
Color is context.
For example, is salmon pink or orange?
Here, I'd call it pink.
Here, it looks closer to orange.
The color of your skin is subjective too.
Depending on what colors you place next to your own face, you can easily make the natural healthy color of your skin look too cool, too warm, too dark, too light, or too vivid - or disappear altogether.
This looks unlovely because it looks unhealthy.
When you know your the natural palette of your body, and put the colors of that palette next to your skin, your skin 's healthy color emerges. You look beautiful because you look healthy.
