....It seems that I was remembering a method for converting a color image to
grayscale, though it might still be applicable here since we're talking about
the visual influence of colors...

From the POV docs, in reference to grayscale output:

  "The brightness of a pixel is calculated in the same way that color images are
converted to grayscale images: height = 0.3 * red + 0.59 * green + 0.11 * blue."

Maybe this helps, maybe it doesn't :/
