How do you get hue from RGB?

5 Answers

  1. Convert the RGB values to the range 0-1, this can be done by dividing the value by 255 for 8-bit color depth (r,g,b – are given values): R = r / 255 = 0.09 G = g / 255 = 0.38 B = b / 255 = 0.46.
  2. Find the minimum and maximum values of R, G and B.
  3. Depending on what RGB color channel is the max value.
