colour.CAM_Specification_RLAB#
- class colour.CAM_Specification_RLAB(J: NDArrayFloat | None = <factory>, C: NDArrayFloat | None = <factory>, h: NDArrayFloat | None = <factory>, s: NDArrayFloat | None = <factory>, HC: NDArrayFloat | None = <factory>, a: NDArrayFloat | None = <factory>, b: NDArrayFloat | None = <factory>)[source]#
Define the RLAB colour appearance model specification.
This specification has field names consistent with the remaining colour appearance models in
colour.appearance
but diverge from Fairchild (2013) reference.- Parameters:
J (NDArrayFloat | None) – Correlate of Lightness \(L^R\).
C (NDArrayFloat | None) – Correlate of achromatic chroma \(C^R\).
h (NDArrayFloat | None) – Hue angle \(h^R\) in degrees.
s (NDArrayFloat | None) – Correlate of saturation \(s^R\).
HC (NDArrayFloat | None) – Hue \(h\) composition \(H^C\).
a (NDArrayFloat | None) – Red-green chromatic response \(a^R\).
b (NDArrayFloat | None) – Yellow-blue chromatic response \(b^R\).
Notes
This specification is the one used in the current model implementation.
