“AstraZeneca had created pharmaceutical marketing history by focusing its promotion on the color of its product rather than on its name or even what it did. The pill’s color had become a marketing tool, with the deep violet color giving it the feel of royalty and instilling loyalty in those who took it. According to industry consultants at IMS Health, AstraZeneca was one of the first drug companies to give their medicines unique shades to strengthen the value of their brand and public identity, just as Coca-Cola has done with the color red and the United Parcel Service with brown. Marketers were giving the pill a personality.

“’Pink is perceived as calming, and may be suitable for heart drugs or tranquilizers, while bold colors such as red suggest rapid action and stimulation, and may therefore be appropriate for a painkiller or antidepressant,’ the IMS consultants wrote in an article in 2001. ‘On the other hand, it is difficult to imagine a pill in black, a color associated with death and morbidity.’

“If some patients did not realize their purple heartburn pill was actually AstraZeneca’s Pilosec, then they did not notice as their doctors switched them to the ‘new’ drug of the same shade but with the turn-of-the-century name Nexium.”

The sky is blue for many “reasons.”

Reason is an “intellectual faculty that adopts actions to ends.”

The left brain says, “I’m late, I’m late, for a very important date.”

The right brain says, “If you don’t care where you’re going, you ain’t lost.”

One of the million reasons the sky is blue is to TIME life on planet Earth.

Scientists say blue light and circadian rhythms co-evolved because life began in the sea.

Close, but no cigar.

Life began on land, not in the ocean.

But it’s true that meat began in the ocean.

The sodium in the ocean provided the flexibility to transform inflexible plant matter into flexible animal matter.

Blue light and circadian rhythms upgraded their relationship after life became flexible in the sea.

Rhythm and blues got funkier in the “seven seas” (actually, an octave).

One definition of “alertness” is a 300 millisecond response, cultivated by 459-484 nanometer light spectra.

In other words, “alertness” is the blink of an eye, assisted by blue light.

Our eyes and brain are especially sensitive to the color blue.

The “school teacher” answer to, “Why is the sky blue?” is …

“It’s caused by diffuse sky radiation.”

Their answer to, “Why is a blue eye blue?” is …

“It’s reflecting blue light.”

Their answer to, “Why do some monkeys have blue buttocks?” is …

“Those monkey butts are reflecting blue light.”

Sherwin-Williams has nothing to do with the blue sky, blue eyes, or blue monkey butts.

John Naylor (Out of the Blue: A 24-Hour Skywatcher’s Guide, 2002) wrote …

“The sky looks blue because sunlight is scattered by molecules in the atmosphere. A molecule scatters about ten times as much blue light as it does red light. Consequently scattered sunlight, called airlight, contains far more blue light than unscattered sunlight. At the same time, forward-scattered light is deficient in blue light. In other words the proportion of red light to blue light is greater than in unscattered sunlight. From a direction perpendicular to the Sun’s rays airlight looks blue, whereas looking towards the Sun the sky looks less blue.”
