Define the Kim, Weyrich and Kautz (2009) colour appearance model specification.

Parameters:

J (float | NDArrayFloat | None) – Correlate of Lightness \(J\).
C (float | NDArrayFloat | None) – Correlate of chroma \(C\).
h (float | NDArrayFloat | None) – Hue angle \(h\) in degrees.
s (float | NDArrayFloat | None) – Correlate of saturation \(s\).
Q (float | NDArrayFloat | None) – Correlate of brightness \(Q\).
M (float | NDArrayFloat | None) – Correlate of colourfulness \(M\).
H (float | NDArrayFloat | None) – Hue \(h\) quadrature \(H\).
HC (float | NDArrayFloat | None) – Hue \(h\) composition \(H^C\).
