Color Theory
Color Theory: Spectral color corresponds to wavelengths of visible light — the root of all color.
The root of all color comes from light. Sunlight, artificial light — all visible light is made up of different wavelengths. And each wavelength corresponds to a different color. This is the spectral color.
The colors of the rainbow — red, orange, yellow, green, blue, indigo and violet — are the spectral colors. They’re the colors that we see when a prism or a raindrop breaks up white light. All other colors are made by mixing spectral colors together.
Theoretically, colors corresponding to wavelengths are infinite, but our human eyes can only see a limited number of colors. The number of spectral colors that we can see depends on the sensitivity of our eyes.
We separate colors by wavelengths (nm). Violet is the color at the shortest wavelength, at around 380 nm. Red is the color at the longest wavelength, at around 700 nm. In between are all the other colors of the rainbow.
When all these colors are combined, we see white light. That’s because white light contains all the colors of the visible spectrum. Black, on the other hand, is the absence of color, and what that means is that black doesn’t contain any of the colors of the visible spectrum.
