“I wished to find out whether a similar bright line could be seen in the spectrum of sunlight as in the spectrum of lamplight, and I found, with the telescope, instead of this, an almost countless number of strong and feeble vertical lines which, however, were darker than the other parts of the spectrum, some appearing to be almost perfectly black.”
Joseph von Fraunhofer's Gesammelte Schriften (1888) p. 10, as quoted by Florian Cajori, A History of Physics in its Elementary Branches http://books.google.com/books?id=eegKAQAAIAAJ (1917)

Context: We are all assumed, these days, to reside at one extreme of the opinion spectrum, or another. We are pro-abortion or anti-abortion. We are free traders or protectionist. We are pro-private sector or pro-big government. We are feminists or chauvinists. But in the real world, few of us holds these extreme views. There is instead a spectrum of opinion.

The Eye of Spirit : An Integral Vision for a World Gone Slightly Mad (1997)
Context: An acknowledgment of the full spectrum of consciousness would profoundly alter the course of every one of the modern disciplines it touches — and that, of course, is an essential aspect of integral studies... A full-spectrum approach to human consciousness and behavior means that men and women have available to them a spectrum of knowing — a spectrum that includes, at the very least, the eye of flesh, the eye of mind, and the eye of spirit.

As quoted in Earth's Aura (1977) by Louise B. Young
Context: What beauty. I saw clouds and their light shadows on the distant dear earth.... The water looked like darkish, slightly gleaming spots.... When I watched the horizon, I saw the abrupt, contrasting transition from the earth's light-colored surface to the absolutely black sky. I enjoyed the rich color spectrum of the earth. It is surrounded by a light blue aureole that gradually darkens, becoming turquiose, dark blue, violet, and finally coal black.
