Colors By Wavelength
Below is a rough table of wavelengths, colors and complementary colors. This utilizes the scientific CMY and RGB color wheels rather than the traditional RYB color wheel.
| Wavelength (nm) | Color | Complementary Color |
|---|---|---|
| 400-424 | Violet | Green-yellow |
| 424-491 | Blue | Yellow |
| 491-570 | Green | Violet |
| 570-585 | Yellow | Blue |
| 585-647 | Orange | Cyan-Blue |
| 647-700 | Red | Cyan |
This can only be used as a very rough guide, for instance if a narrow range of wavelengths within the band 647-700 is absorbed, then the blue and green receptors will be fully stimulated, making cyan, and the red receptor will be partially stimulated, diluting the cyan to a greyish hue.

Famous quotes containing the word colors:
“[The Declaration of Independence] meant to set up a standard maxim for free society, which should be familiar to all, and revered by all; constantly looked to, constantly labored for, and even though never perfectly attained, constantly approximated, and thereby constantly spreading and deepening its influence, and augmenting the happiness and value of life to all people of all colors everywhere.”
—Abraham Lincoln (1809–1865)
