Spectrum or spectra
The electronic structure of the iron ions that are contained in it. Iron is a transition metal, and transition metal compounds tend to be highly colored because they have absorption bands in the visible spectrum.
The fact the solution is colored means that it absorbs (or interacts at least) with visible (since you can see it!). Generally such compounds are characterized using visible light, but also ultraviolet (UV) and infrared (IR) which are the two regions of the electromagnetic spectrum adjacent to visible light. This type of analysis is generally called UV/visible spectroscopy (although it frequently also extends into the near IR region).
the answer is pigments
colored light spectrum
A spectrum
fluorescence
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.
Spectrum or spectra
This is called the (visible) spectrum; and may also be referred to as a rainbow.
Most of the spectrum charts that I have seen are listed in wavelengths, particularly nanometers (nm). Where 1 nm = 1x10^-9 m.
White or sunlight -- the sun emits light very close to your description. =====================================

of the color between green and orange in the spectrum, a primary subtractive color complementary to blue; colored like ripe lemons or egg yolks.
The colour spectrum - it runs from red through orange, yellow, green, blue and indigo to violet.
