A spectral color is a color that is evoked by a single wavelength of light in the visible spectrum, or by a relatively narrow band of wavelengths, also known as monochromatic light. Every wavelength of light is perceived as a spectral color, in a continuous spectrum; the colors of sufficiently close wavelengths are indistinguishable.
The spectrum is often divided up into named colors, though any division is somewhat arbitrary: the spectrum is continuous. Traditional colors include: red, orange, yellow, green, blue, and violet.
One needs at least trichromaticcolor vision for there to be a distinction between spectral and non-spectral colours: trichromacy gives a possibility to perceive both hue and saturation in the chroma. In color models capable to represent spectral colors, such as CIELUV, a spectral color has the maximal saturation among all colors of the same hue.
Color in Our World | The Electromagnetic Spectrum | Arbor Scientific
Our eyes are sensitive only to a narrow region of the electromagnetic spectrum which we call visible light. By convention, the hues are grouped into seven colors—red, orange, yellow, green, blue, indigo, and violet. Watch as we discuss the electromagnetic spectrum in more detail in this video.

Magenta: The colour that doesn't exist – BBC REEL
When we look at a rainbow, we see a full spectrum of light. Every colour we could imagine. Except one – magenta.
Where is it? Well, officially magenta doesn't exist. There is no wavelength of light for magenta, meaning the human brain literally makes it up, but how?

Contrary to prevailing scientific opinion, Newton felt colours were already present in White light and it was not impurities found in the Prism that gave the Rainbow effect. Subscribe to Earth Science: http://bit.ly/SubscribeToEarthLab
What set Newton apart from other scientists was that he famously devised and performed an experiment to test his hypothesis.

How we see color - Colm Kelleher
View full lesson: http://ed.ted.com/lessons/how-we-see-color-colm-kelleher
There are three types of color receptors in your eye: red, green and blue. But how do we see the amazing kaleidoscope of other colors that make up our world? Colm Kelleher explains how humans can see everything from auburn to aquamarine.
Talk by Colm Kelleher, animation by TED-Ed.

Non-spectral colours (colours that aren't in the rainbow) can only exist as mixtures of other colours. All of the shades of purple, magenta and pink are non-spectral and this can be shown by using dispersing light and using a pink filter to find it's constituent colours.

Classification of Stars: Spectral Analysis and the H-R Diagram
So we have made it through the dark ages, and are now a few hundred million years into the lifetime of the universe. There are plenty of stars all over the place, but are they all the same? How can we classify stars? Let's go through the basics of the Harvard System, and then take a look at something called a Hertzsprung-Russell diagram.

Spectral Data 101: How to Communicate Color Data
What is a spectrophotometer, and when should it be used? Whether it is for color identification, color matching, or color quality control, these instruments can help you achieve and communicate accurate color. During this quick webinar, Ed Hattenberger, Senior Color Scientist at X-Rite Pantone will briefly discuss why spectral data is important for color communication, the common types of geometries of spectrophotometers and why spectral data is preferred over CIELAB color values.
