if you go to the wikipedia site and look up the word blue, you'll be able to learn all sorts of amazing and wonderful things about the word itself, the emotions behind it (which is why, as you can see, i went there this morning). grand instance: in the vietnamese language, both tree leaves and the sky are xanh (to distinguish, one may use xanh lá cây "leaf grue" for green and xanh nước "water grue" for blue). meaning, there is one word for blue and green, apparently? a clear sky on a sunny day appears blue because of rayleigh scattering of the light from the sun. large quantities of water appear blue because red light is absorbed as an overtone of the O-H stretching vibration. heavy water is colorless, because the absorption band is outside the visible spectrum. (bet you didn't know that, did you?).
blue often denotes injury, as in the phrase "black and blue" since it is the color of a bruise. blue is used also as a word to denote a sad or melancholy state, as in depression, or simply a state of deep contemplation (although the phrase "blue skies," referring to sunny weather, implies cheerfulness). symbolically, blue is associated with that state, such as the term "blue period" to describe pablo picasso's work from 1901 to 1904.
blue is considered a calming, soothing color, perhaps related to its association with water and to the sky.
in House of Leaves every instance of the word House is in blue.
On Being Blue: A Philosophical Inquiry is a book-length essay by william h. gass.
in astronomy, a blue moon is the second full moon in a calendar month, the third full moon in a season that has four, or a moon that appears blue because of particles in the atmosphere. All are uncommon enough that the expression "once in a blue moon" means "once in a great while" or "infrequently."
bluebirds are any of the north american songbirds in the genus sialia: eastern bluebird (Sialia sialis), western bluebird (Sialia mexicana), or mountain bluebird (Sialia currucoides). They are medium-sized thrushes that usually have blue plumage and, in males, a rust-color breast. and, i am noting here, are the animal commonly used as a symbol for happiness. my father says his mother used to blow a kiss every time she spotted one, "for good luck".
the mountains surrounding me here are called the blue ridge, and they are, indeed, blue. blue as heavy smoke, sometimes, and that is why they call this general area the smoky mountains.
home seems mighty blue right now. as roy was saying about his bedroom oriental rug, which he carted off to his dorm room at school, its rosy brick red colors make him think of the colors of our home, all brick reds and salmons and yes, soft blues and ochres and shades of soft greens. bless his heart. i love that about my boys: they can appreciate colors that surround their days, can absorb the details of their everyday lives without ignoring them. the fact that both boys detest overhead lights, that roy and i spent a good amount of time in thrift stores the other day searching for two table lamps that would create a nice warm lighting in his room gives me hope that he'll not be feeling the dismal, sickly blue of god-awful fluorescent lights.
meanwhile? i think i'll go outside and stare up at the azure sky.
