What Does Indigo Mean?<\/span><\/h2>\n

Indigo is a spectral color between blue and violet at about 420 to 450 nanometers (nm) in wavelength.<\/p>\n

Today\u2019s color scientists do not often recognize indigo as a separate color division and place it between blue and violet.<\/p>\n

Techopedia Explains Indigo<\/span><\/h2>\n

Any wavelength of less than 450 nm is simply referred to as violet. Here are the color frequency wavelengths:<\/p>\n

    \n
  • Violet 380\u2013450 nm<\/li>\n
  • Indigo is about 435 nm<\/li>\n
  • Blue 450\u2013475 nm<\/li>\n
  • Cyan 476\u2013495 nm<\/li>\n
  • Green 495\u2013570 nm<\/li>\n
  • Yellow 570\u2013590 nm<\/li>\n
  • Orange 590\u2013620 nm<\/li>\n
  • Red 620\u2013750 nm<\/li>\n<\/ul>\n

    Isaac Newton originally divided the color spectrum into the seven colors: red, orange, yellow, green, blue, indigo, and violet. Although indigo is traditionally one of seven divisions in the optical spectrum, the human eye is relatively insensitive to indigo\u2019s frequencies. In fact, some well-sighted people cannot distinguish indigo from blue or violet.<\/p>\n

    The color electric indigo is the brightest version of indigo on a computer screen, and is located between Web blue and violet on the RGB color wheel. Deep indigo is another name for the Web color blue\/violet, which is brighter than the Web color indigo but not as bright as electric indigo.<\/p>\n

    Electric indigo may be used as a glow color in computer graphics lighting. It is said to change color from indigo to lavender when blended with white.<\/p>\n","protected":false},"excerpt":{"rendered":"
