Why Purple Is Not a Real Color: The Science Explained

Discover why purple isn't classified as a real color in this insightful explanation of light wavelengths and color perception.

299 views

Purple is not a real color because it does not correspond to a single wavelength of light. Instead, it is a composite color perceived by our brains when both red and blue light are present. Unlike spectral colors (red, orange, yellow, green, blue, indigo, violet), which have specific wavelengths, purple results from the combination of red and blue light. Our brains interpret this mixture as purple, even though it has no wavelength in the visible spectrum.

FAQs & Answers

  1. Why can't purple be found in a rainbow? Purple cannot be found in a rainbow because it is not a spectral color; it is a result of mixing red and blue light.
  2. What are the primary colors used to create purple? Purple is created by mixing the primary colors red and blue.
  3. What is the difference between real colors and composite colors? Real colors correspond to specific wavelengths of light, while composite colors like purple are perceived when two or more wavelengths are mixed.
  4. Is indigo considered a real color? Yes, indigo is considered a real color as it has a specific wavelength in the visible spectrum.
