Spectral Colors
| Color | Frequency | Wavelength |
|---|---|---|
| violet | 668–789 THz | 380–450 nm |
| blue | 606–668 THz | 450–495 nm |
| green | 526–606 THz | 495–570 nm |
| yellow | 508–526 THz | 570–590 nm |
| orange | 484–508 THz | 590–620 nm |
| red | 400–484 THz | 620–750 nm |
Colors that can be produced by visible light of a narrow band of wavelengths (monochromatic light) are called pure spectral colors. The various color ranges indicated in the diagram on the right are an approximation: the spectrum is continuous, with no clear boundaries between one color and the next.

Famous quotes containing the words spectral and/or colors:
“How does one kill fear, I wonder? How do you shoot a spectre through the heart, slash off its spectral head, take it by its spectral throat?”
—Joseph Conrad (1857–1924)
“Then, bringing me the joy we feel when wee see a work by our favorite painter which differs from any other that we know, or if we are led before a painting of which we have until then only seen a pencil sketch, if a musical piece heard only on the piano appears before us clothed in the colors of the orchestra, my grandfather called me the [hawthorn] hedge at Tansonville, saying, “You who are so fond of hawthorns, look at this pink thorn, isn’t it lovely?””
—Marcel Proust (1871–1922)
