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 \(H^C\).
