  Using PNG transparency (alpha channel) as background mask
  From reference white:  
  To reference white: D65
  Converting 1000 randomly selected pixel(s) from sRGB color space to Lab color space
  Accuracy of CIE Lab color space depends on specification of an appropriate white reference. See 'Color spaces' vignette for more information.
  Using 2^3 = 8 total bins
  New names:
  * `B` -> `B...4`

  Using PNG transparency (alpha channel) as background mask
  RGB and HSV are device-dependent, perceptually non-uniform color spaces. See 'Color spaces' vignette for more information.
