colour.adaptation.chromatic_adaptation_forward_CMCCAT2000#

Adapt the specified stimulus CIE XYZ tristimulus values from test viewing conditions to reference viewing conditions using the CMCCAT2000 forward chromatic adaptation model.

Parameters:

XYZ (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 100]) – CIE XYZ tristimulus values of the stimulus to adapt.
XYZ_w (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 100]) – Test viewing condition CIE XYZ tristimulus values of the whitepoint.
XYZ_wr (Annotated[_Buffer | _SupportsArray[dtype[Any]] | _NestedSequence[_SupportsArray[dtype[Any]]] | complex | bytes | str | _NestedSequence[complex | bytes | str], 100]) – Reference viewing condition CIE XYZ tristimulus values of the whitepoint.
L_A1 (ArrayLike) – Luminance of test adapting field \(L_{A1}\) in \(cd/m^2\).
L_A2 (ArrayLike) – Luminance of reference adapting field \(L_{A2}\) in \(cd/m^2\).
surround (InductionFactors_CMCCAT2000) – Surround viewing conditions induction factors.

Returns:

CIE XYZ tristimulus values of the stimulus corresponding colour.

Return type:

numpy.ndarray
