colour.matrix_RGB_to_RGB#

Compute the matrix \(M\) converting from the specified input RGB colourspace to the specified output RGB colourspace using the specified chromatic adaptation method.

Parameters:

input_colourspace (RGB_Colourspace | LiteralRGBColourspace | str) – RGB input colourspace.
output_colourspace (RGB_Colourspace | LiteralRGBColourspace | str) – RGB output colourspace.
chromatic_adaptation_transform (LiteralChromaticAdaptationTransform | str | None) – Chromatic adaptation transform. If None, no chromatic adaptation is performed.

Returns:

Conversion matrix \(M\).

Return type:

numpy.ndarray

Examples

>>> from colour.models import (
...     RGB_COLOURSPACE_sRGB,
...     RGB_COLOURSPACE_PROPHOTO_RGB,
... )
>>> matrix_RGB_to_RGB(RGB_COLOURSPACE_sRGB, RGB_COLOURSPACE_PROPHOTO_RGB)
...
