colour.notation.munsell_value_ASTMD1535

colour.notation.munsell_value_ASTMD1535(Y: Domain100) → Range10

Compute the Munsell value \(V\) from the specified luminance \(Y\) using an inverse lookup table from ASTM D1535-08e1 method.

Parameters:

Y (Domain100) – Luminance \(Y\).

Returns:

Munsell value \(V\).

Return type:

np.float or numpy.NDArrayFloat

Notes

Domain	Scale - Reference	Scale - 1
Y	100	1

Range	Scale - Reference	Scale - 1
V	10	1

• The Munsell value computation with ASTM D1535-08e1 method is only defined for domain [0, 100].
