Color picker based on human perception
Color picker that arranges colors the way the human eye perceives colors. Physically correct with wavelength, CIE 1931 XYZ specification, and hex and RGB support.
This arranges colors by physiologically perceived colors, based on human color vision. We take real-world color wavelengths and calculate them into RGB triplets.
RGB to Wavelength
The color triangle follows the actual rec.2020 specification for your monitor on how to draw a color. Each pixel you see has its color calculated to match the wavelength at that particular x,y-coordinate. The line from the center crosses the spectrum line (the red horseshoe) exactly at the wavelength of that selected color.
  • New: full alpha support
