Maybe that's why Maxfield Parrish (1870-1966) was so successful in his blue-themed paintings of twilight, such as "Stars," above.
How we artificially light our indoor environments can help, too. According to the New York Times article:
"Artificial light has been around for more than 120 years. But the light emitted by older sources, like incandescent bulbs, contains more red wavelengths. The problem now, Dr. Brainard and other researchers fear, is that our world is increasingly illuminated in blue. By one estimate, 1.6 billion new computers, televisions and cellphones were sold last year alone, and incandescent lights are being replaced by more energy-efficient, and often bluer, bulbs."
