Most of the spectrum charts that I have seen are listed in wavelengths, particularly nanometers (nm). Where 1 nm = 1x10^-9 m.
The wavelength of a wave (the amount of energy the wave carries) determines its placement on the spectrum of visible light.
colored light spectrum
A spectrum
This is called the (visible) spectrum; and may also be referred to as a rainbow.

No, a compound doesn't need to be colored to be separated by chromatography. There are plenty of detectors that can be used outside of the visible spectrum, and in fact don't even use spectroscopic methods, such as Electron Capture detection (ECD).

colored light spectrum
A spectrum
All colored materials, except white-colored and black-colored materials, reflects or emits its own color of light while the other parts of the spectrum are absorbed. White-colored and black-colored materials are exceptions because, white-colored materials reflects all the colors or all the parts of the visible spectrum because white's composition is all the colors and, black-colored materials absorb all the colors while reflecting none because black is merely the absence of any color although black is sometimes described as a color. In other words, white is composed of all the parts of the visible spectrum that is why white-colored materials reflect all the light. In the other hand, black do not reflect any color or any part of the visible spectrum but absorb all of it because black is the absence of spectral light or simply the absence of light.

The word 'colored' is the present participle, present tense of the verb to color. The present participle of the verb also functions as an adjective.The word color is both a verb and a noun.The noun 'color' is a word for the property possessed by an object that determines the way the object reflects light; a word for a thing.The noun forms of the verb to color are colorer and the gerund, coloring.
White or sunlight -- the sun emits light very close to your description. =====================================
transition of an electron from a higher energy level to a lower energy level.
They are both light colored crystals that dissolve in water.
