What makes this photo identifiable as dawn instead of sunset? Hint: it’s the color. We expect sunsets to be warm, but mornings to be cool and clear.

Today’s post is one from the archives; back nearly to the beginnings of the site. I’m pulling it out again to set you up for what comes next. 

A series of experiments was done many years ago that showed humans have been conditioned to expect certain things in the way of color: blue ketchup just doesn’t fly, for instance. The theory is that it’s a primeval subconscious response to warn us of danger. Think of it this way: rancid meat looks a certain way, and has a certain color. Even if we can’t smell it – looking at a photograph of vomit or something decomposing makes us go ewwww. Such examples are to be found in nature all the time – think of those brightly colored poisonous beetles, for instance. In fact, the link between color and range (and thus emotion) is so strong that many species mimic the coloring of more dangerous species to warn away predators, but at the same time rely solely on that as protection because they pack no venom or toxicity. (Toxicity is energy-consuming to produce, and in food-scarce environments, you want to waste as little of your nutritional intake as possible producing something that’s only going to help you if you’re eaten – and thus probably going to die anyway.)
