rm note about srGB weights

not sure if they really depend on human perception or if they are just
the amount of light emitted by the different colors parts in a pixel

@@ -127,9 +127,7 @@ Colors on the web are defined in the [sRGB color space]. The first part of this
  127   127 formula is the official formula to convert a sRGB color to luminance. Doubling
  128   128 sRGB values (e.g. from `#444` to `#888`) does not actually double the physical
  129   129 amount of light, so the first step is a non-linear "gamma decoding". Then the
  130    -1 red, green, and blue channels are weighted to sum to the final luminance. The
  131    -1 weights result from different sensitivities in the human eye: Yellow light has
  132    -1 a much bigger response than the same amount of blue light.
