Humans Change Color

In 2018, researchers proved that idioms such as “green with envy” were not just prose. Depending on the emotion, human faces really do change color. This chameleon habit, which is linked to blood flow, is very subtle. Most of the time, hues are so light that other people only subconsciously pick up on the person’s true emotions.
The affected areas curve around the eyebrows, cheeks, chin, and nose. With the help of a computer program and an understanding of how humans see color, scientists revealed facial rainbows for the first time.
Disgust bloomed as a blue-yellow shadow around the mouth and colored the forehead and the nose with red-green. Happiness infused the cheeks and temples with red but tinted the chin blue. Strangely, “surprise” was close to “happiness,” with a redder forehead and a chin with less blue.
Looking at pictures of a neutral face, volunteers were mostly able to pick the right emotion when its colors were superimposed on the image. Other pictures showed the wrong shades for an expression—for example, happy colors on an angry face. But the volunteers instinctively felt that something was wrong, although they could not say what.
Probably a good thing to work on improving now that the holidays are almost here. You don't want your true feelings to show too much when your better half gives you that ugly hand made sweater...right?
Coffee in the kitchen this morning. Lemon creme cookies are handy!
