Colour 0.3.15 - Alpha Milestone

This is mainly a maintenance release implementing support for Python 3.8, Numpy 1.18 and fixing a major issue in Krystek (1985) correlated colour temperature computation.

Features

colour.colorimetry

  • The typical CIE LED illuminants spectral power distributions and chromaticity coordinates have been added to the datasets: (@KelSolaar)
    • LED-B1
    • LED-B2
    • LED-B3
    • LED-B4
    • LED-B5
    • LED-BH1,
    • LED-RGB1
    • LED-V1
    • LED-V2
  • The recommended indoor illuminants ID65 and ID50 spectral power distributions and chromaticity coordinates have been added to the datasets. (@KelSolaar)
  • Add colour.colorimetry.sds_and_multi_sds_to_multi_sds definition that converts given spectral and multi-spectral distributions to multi-spectral distributions. (@KelSolaar)

colour.models

Fixes

colour

Various fixes have been implemented to ensure compatibility with Python 3.8 and Numpy 1.18. (@KelSolaar, @MaxSchambach, @mzszym)

colour.io

colour.notation

  • Fix incorrect Domain-Range scale in Munsell Renotation System implementation. (@KelSolaar)

colour.temperature

  • colour.temperature.CCT_to_uv_Krystek1985 definition was incorrectly implemented. Incorrect reading of the reference publications ended up with exponentiations being different, e.g. 10**4 was replaced with 10e4. (@OlliNiemitalo)

Changes

colour.algebra

  • colour.algebra.cartesian_to_spherical and colour.algebra.spherical_to_cartesian use ISO conversion convention. ρ is in range [0, +inf], θ is in range [0, pi] radians, i.e. [0, 180] degrees, and φ is in range [-pi, pi] radians, i.e. [-180, 180] degrees.

colour.volume

  • colour.is_within_visible_spectrum: (@KelSolaar)
    • Signature: XYZ_outer_surface(XYZ, cmfs=STANDARD_OBSERVERS_CMFS['CIE 1931 2 Degree Standard Observer'].clone().align(DEFAULT_SPECTRAL_SHAPE_XYZ_OUTER_SURFACE), illuminant=sd_ones(DEFAULT_SPECTRAL_SHAPE_XYZ_OUTER_SURFACE), tolerance=None, **kwargs)
  • colour.volume.XYZ_outer_surface: (@KelSolaar)
    • Signature: XYZ_outer_surface(cmfs=STANDARD_OBSERVERS_CMFS['CIE 1931 2 Degree Standard Observer'].clone().align(DEFAULT_SPECTRAL_SHAPE_XYZ_OUTER_SURFACE), illuminant=sd_ones(DEFAULT_SPECTRAL_SHAPE_XYZ_OUTER_SURFACE), **kwargs)
    • Implementation: The generated CIE XYZ tristimulus values are not normalised anymore, this will only affect computation if a different illuminant than CIE Illuminant E is chosen.

colour.plotting

  • colour.plotting.common.wrap_title: (@KelSolaar)
    • Remove
