This blue marble

– and yet it spins

Colors seen and unseen

spectrum-1The low, early January sun found its way in through the dining room window just so. It hit the crystal chandelier and exploded into hundreds of little rainbows, all over the walls and the ceiling and the fireplace. For a long while the dining room became a crystal palace.

White light does not contain every color as such. In a way it kind of does, but when one breaks down white light into pure spectral colors there will be red, orange, yellow, green, blue, and violet. Pink and brown for example are not spectral colors and are instead blends of two or more colors. But why is violet (essentially blue and red mixed) a spectral color and not pink or purple, with just a bit less blue and more red? And how many colors are we actually missing because our human eyes cannot distinguish them? Ultraviolet and infrared probably, but are there amazing iridescent turquoises and greens and shades of yellow and even entirely imaginary colors that only bees and butterflies can see? If the electromagnetic spectrum stretches from meter-long radio waves into micro waves into that tiny band we perceive as colors – and then out into X-ray waves, what would the world look like if we were to perceive for example micro waves and X-ray waves as colors?spectrum-2(Loviisa, Finland; January 2019)
