colour.plotting.lines_daylight_locus(mireds: bool = False, method: Literal['CIE 1931', 'CIE 1960 UCS', 'CIE 1976 UCS'] | str = 'CIE 1931') → Tuple[ndarray[Any, dtype[_ScalarType_co]]][source]#

Return the Daylight Locus line vertices, i.e. positions, normals and colours, according to given method.

Parameters:

  • mireds (bool) – Whether to use micro reciprocal degrees for the iso-temperature lines.

  • method (Literal['CIE 1931', 'CIE 1960 UCS', 'CIE 1976 UCS'] | str) – Daylight Locus method.

Returns:

Tuple of Spectral Locus vertices.

Return type:

tuple

Examples

>>> lines = lines_daylight_locus()
>>> len(lines)
1
>>> lines[0].dtype
dtype([('position', '<f8', (2,)), ('normal', '<f8', (2,)), ('colour', '<f8', (3,))])
