ColorConverter - Conversion Flow

The Colorimetric Calculator

Introduction
Conversion flow
Input specifications
Technical specifications

You enter a source color into its corresponding fields, press to Go button on the keyboard and all the other modes are calculated. The internal flow of conversion is shown here:

For example if you enter a RGB color, say Adobe RGB, the app calculates values of other modes in this order:

• in the RGB space illuminant (for Adobe RGB this is D65)
  • RGB (source mode)
  • HSB (from RGB)
  • HSL (form RGB)
  • Hexadecimal (from RGB)
  • XYZ (from RGB);
  • Yxy (from XYZ)
  • Helmholtz coordinates (from Yxy)
  • correlate color temperature (kelvin, from XYZ)
  • mired (from correlate color temperature)
  • Lab (from XYZ)
  • LCh (from Lab)
• in the reference illuminant (if different from RGB space illuminant)
  • XYZ (calculated with the CAT indicated)
  • Yxy (from XYZ)
  • Helmholtz coordinates (from Yxy)
  • correlate color temperature (kelvin, from XYZ)
  • mired (from correlate color temperature)
  • Lab (from XYZ)
  • LCh (from Lab)
Reference illuminant can be the same as the RGB space illuminant, or can be a different illuminant. In the latter case (two different illuminants) the conversion is made with a chromatic adaptation transform and XYZ acts as a link between the first group of color modes and the second one.
