colour.difference.delta_E_CAM16UCS

colour.difference.delta_E_CAM16UCS(Jpapbp_1, Jpapbp_2)

Returns the difference \(\Delta E'\) between two given Li et al. (2017) CAM16-UCS colourspaces \(J'a'b'\) arrays.

Parameters:
  • Jpapbp_1 (array_like) – Standard / reference Li et al. (2017) CAM16-UCS colourspaces \(J'a'b'\) array.
  • Jpapbp_2 (array_like) – Sample / test Li et al. (2017) CAM16-UCS colourspaces \(J'a'b'\) array.
Returns:

Colour difference \(\Delta E'\).
Return type:

numeric or ndarray
