Visible spectrum - Wikipedia
The visible spectrum is the band of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light (or simply light). The optical spectrum is sometimes considered to be the same as the visible spectrum, but some authors define the term more broadly, to include the ultraviolet and infrared par… See more

- 400 nm (violet) to 700 nm (red)Humans color spectrum refers to the range of wavelengths of light that humans can see, from about 400 nm (violet) to 700 nm (red)12. This is also called the visible spectrum, and it consists of seven regions of color: red, orange, yellow, green, blue, indigo, and violet3. Humans can see different colors when light hits an object and some of it is absorbed and some is reflected4. Humans have three types of cone cells in the eye that can register about 100 different color shades each, resulting in about one million possible colors5.Learn more:✕This summary was generated using AI based on multiple online sources.

The human eye sees color over wavelengths ranging roughly from 400 nanometers (violet) to 700 nanometers (red). Light from 400–700 nanometers (nm) is called visible light, or the visible spectrum because humans can see it. Light outside of this range may be visible to other organisms but cannot be perceived by the human eye.
www.thoughtco.com/understand-the-visible-spectru…The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. Essentially, that equates to the colors the human eye can see. It ranges in wavelength from approximately 400 nanometers (4 x 10 -7 m, which is violet) to 700 nm (7 x 10 -7 m, which is red).www.thoughtco.com/the-visible-light-spectrum-269…The spectrum, obtained by refracting light through a prism, shows a number of characteristic regions of colour —red, orange, yellow, green, blue, indigo, and violet.www.britannica.com/science/human-eye/Colour-vis…The visible spectrum for humans falls between ultraviolet light and red light. Scientists estimate that humans can distinguish up to 10 million colors. When light hits an object, such as a lemon, the object absorbs some of that light and reflects the rest of it.
www.aao.org/eye-health/tips-prevention/how-huma…Researchers estimate that most humans can see around one million different colors. This is because a healthy human eye has three types of cone cells, each of which can register about 100 different color shades, amounting to around a million combinations. Of course, this will vary for people who have a color impairment (or are ‘colorblind’).www.pantone.com/articles/color-fundamentals/ho… Visible Light - NASA Science

Color vision - Wikipedia
Color is a feature of visual perception by an observer. There is a complex relationship between the wavelengths of light in the visual spectrum and human experiences of color. Although most people are assumed to have the same mapping, the philosopher John Locke recognized that alternatives are possible, and described one such hypothetical case with the "inverted spectrum" thought experiment. For example, someone with an inverted spectrum might experience green …
