March|April 2004 How I Lost the Big One When Eric Eldred's crusade to save the public domain reached the Supreme Court, it needed the help of a lawyer, not a scholar. By Lawrence Lessig IT IS OVER A YEAR LATER AS I WRITE THESE WORDS.

Colors and Colorimetry. Physical and biological color Note: All images on this page are drawn in the sRGB colors space, which is something of a standard (if arguably a poor one). If your monitor does sRGB (many of them do), please put it in that mode for the descriptions to be accurate; if your browser and system are intelligent, however, and know about your monitor's colorimetry, you may not have to do this—in fact, the opposite may be the case, you may ruin things by using the wrong correction. There's a (very poor) experimental test you can run at the bottom of this page.

What is light? Light is the region of the electromagnetic spectrum which the unaided human eye can perceive. On the blue (short wavelength) end, the limit is rather sharp and we can put it at a wavelength of 390nm (a frequency of 770THz) for extreme violet. An elementary light stimulus is an arbitrary mixture of the pure lights of the spectrum. A light (a spectrum) is said to be monochromatic What is color? Rods , while the other is called cones or.
