The several colored and other rays of which light is composed, separated by the refraction of a prism or other means, and observed or studied either as spread out on a screen, by direct vision, by photography, or otherwise. See Illust. of Light, and Spectroscope.
A luminous appearance, or an image seen after the eye has been exposed to an intense light or a strongly illuminated object. When the object is colored, the image appears of the complementary color, as a green image seen after viewing a red wafer lying on white paper. Called also ocular spectrum.
Red is such an interesting color to correlate with emotion, because it's on both ends of the spectrum. On one end you have happiness, falling in love, infatuation with someone, passion, all that. On the other end, you've got obsession, jealousy, danger, fear, anger and frustration. Taylor Swift
The past, like the future, is indefinite and exists only as a spectrum of possibilities. Stephen Hawking
Mild autism can give you a genius like Einstein. If you have severe autism, you could remain nonverbal. You don't want people to be on the severe end of the spectrum. But if you got rid of all the autism genetics, you wouldn't have science or art. All you would have is a bunch of social 'yak yaks.' Temple Grandin
To control the breathing is to control the mind. With different patterns of breathing, you can fall in love, you can hate someone, you can feel the whole spectrum of feelings just by changing your breathing. Marina Abramovic
We have all kinds of limitations as human beings. I mean we can't see the whole electromagnetic spectrum; we can't see the very small; we can't see the very far. So we compensate for these short comings with technological scaffoldings. The microscope allows us to extend our vision into the micro-sphere. Jason Silva
