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 to, importance and/or vision:
“I ascribe a basic importance to the phenomenon of language.... To speak means to be in a position to use a certain syntax, to grasp the morphology of this or that language, but it means above all to assume a culture, to support the weight of a civilization.”
—Frantz Fanon (1925–1961)
“The importance of a lost romantic vision should not be underestimated. In such a vision is power as well as joy. In it is meaning. Life is flat, barren, zestless, if one can find one’s lost vision nowhere.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 1, ch. 19 (1962)
“And taken by light in her arms at long and dear last
I may without fail
Suffer the first vision that set fire to the stars.”
—Dylan Thomas (1914–1953)
