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:
“Shall we then judge a country by the majority, or by the minority? By the minority, surely. ‘Tis pedantry to estimate nations by the census, or by square miles of land, or other than by their importance to the mind of the time.”
—Ralph Waldo Emerson (1803–1882)
“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)
