Importance To Vision
Additive color mixing—red and green combining to make yellow, for example, or blue and yellow producing white—runs counter to the commonsense observation that, for example, yellow paint plus cyan paint makes green paint. In this case, one must understand that the wavelengths of light that reach the eye are often selected via these more intuitive subtractive processes: for example, cyan paint appears to our eye as cyan because it absorbs red wavelengths, and a yellow paint appears yellow because it absorbs blue wavelengths. When white light falls on a combination of cyan and yellow, then, both red and blue are absorbed, and green is reflected to the eye.

Famous quotes containing the words importance and/or vision:
“More than ten million women march to work every morning side by side with the men. Steadily the importance of women is gaining not only in the routine tasks of industry but in executive responsibility. I include also the woman who stays at home as the guardian of the welfare of the family. She is a partner in the job and wages. Women constitute a part of our industrial achievement.”
—Herbert Hoover (1874–1964)
“To stroll is a science, it is the gastronomy of the eye. To walk is to vegetate, to stroll is to live.... To stroll is to enjoy, it is to assume a mind-set, it is to admire the sublime pictures of unhappiness, of love, of joy, of graceful or grotesque portraits; it is to plunge one’s vision to the depths of a thousand existences: young, it is to desire everything; old, it is to live the life of the young, to marry their passions.”
—Honoré De Balzac (1799–1850)
