Colour v0.3.16 Release Notes
Release Date: 2020-11-27 // about 4 years ago-
Colour 0.3.16 - Alpha Milestone
๐ This release integrates all the GSoC work from Pawel (@enneract), most of the code from Nishant (@njwardhan) and, the optimizations from Omar (@OmarWagih1). We would like to thank them again for their great contributions!
๐ With this release, we stop testing for Python 3.5 and, Scipy>=1.1.0 becomes the minimum version. This is the last feature release to support Python 2.7! We will also trim the deprecation code in the next version thus, please make sure to update your code accordingly.
The
colour.SpectralDistribution.interpolateandcolour.MultiSpectralDistributions.interpolatemethods now honour class instantiation time interpolation parameters instead of blindly applying CIE 167:2005 recommendation, this introduces minor numerical changes.Many definitions, methods and, module attributes have been renamed to improve consistency and we are reaching a satisfactory point in that regard, hopefully, the names will be much more stable from now on.
๐ Features
colour.algebra- โ Add
colour.algebra.smoothstepdefinition. (@KelSolaar)
colour.characterisation- Support for ACES Input Device Transform (IDT) generation: The implementation follows to some extent RAW to ACES v1 and P-2013-001 procedure. (@KelSolaar)
Usage is simple and as follows:
\>\>\> sensitivities = colour.CAMERA\_RGB\_SPECTRAL\_SENSITIVITIES['Nikon 5100 (NPL)']\>\>\> illuminant = colour.ILLUMINANT\_SDS['D55']\>\>\> colour.matrix\_idt(sensitivities, illuminant)array([[0.46579991, 0.13409239, 0.01935141], [0.01786094, 0.77557292, -0.16775555], [0.03458652, -0.16152926, 0.74270359]])The following ISO 7589 and 6728 spectral data has been added: (@KelSolaar)

colour.modelsGSoC - 2020
Add
colour.models.log_encoding_Log2andcolour.models.log_decoding_Log2log encoding and decoding definitions. (@njwardhan, @KelSolaar)Add

colour.models.logarithmic_function_basic,colour.models.logarithmic_function_quasilogandcolour.models.logarithmic_function_cameradefinitions. (@njwardhan, @nick-shaw, @KelSolaar)Implement support for IGPGTG colourspace by Hellwig and Fairchild (2020) with the
colour.XYZ_to_IGPGTGandcolour.IGPGTG_to_XYZdefinitions. (@KelSolaar)Implement support for DaVinci Wide Gamut colourspace. (@KelSolaar)
colour.plotting- Implement support for ANSI/IES TM-30-18 Colour Rendition Report. (@enneract, @KelSolaar)
- ๐ Implement support for RGB colourspaces chromatic adaptation in various plotting routines: (@KelSolaar)
colour.qualityGSoC - 2020
- Implement support for CIE 2017 Colour Fidelity Index quality metric computation
colour.quality.colour_fidelity_index_CIE2017definition. (@enneract) - Implement support for ANSI/IES TM-30-18 Colour Fidelity Index quality metric computation
colour.quality.colour_fidelity_index_ANSIIESTM3018definition. (@enneract)
colour.recoveryGSoC - 2020
- Implement support for Jakob and Hanika (2019) spectral upsampling method with the
colour.recovery.XYZ_to_sd_Jakob2019definition. (@enneract, @KelSolaar) - Implement support for Mallett and Yuksel (2019) spectral upsampling method with the

colour.recovery.XYZ_to_sd_Otsu2018definition. (@enneract, @KelSolaar)
colour.utilities- Float precision can be set globally with the
colour.utilities.set_float_precisiondefinition and theCOLOUR_SCIENCE__FLOAT_PRECISIONenvironment variable. It will affect almost the entire API and lead to increase performance at the price of broken capabilities. (@KelSolaar) - It is now possible to pass an
axisargument to thecolour.utilities.metric_mseandcolour.utilities.metric_psnrdefinitions. (@KelSolaar) - โ Add
colour.utilities.LazyCaseInsensitiveMappingclass for lazily loading slow and heavy datasets. (@KelSolaar)
๐ Fixes
colour.characterisation- The Finlayson, MacKiewicz and Hurlbert (2015) colour correction method was defective when root-polynomial expansion is in use. (@ChunHsinWang, @KelSolaar)
colour.colorimetry- The
colour.SpectralDistribution.align,colour.MultiSpectralDistributions.align,colour.SpectralDistribution.interpolateandcolour.MultiSpectralDistributions.interpolatemethods did not honour the instantiation time interpolation class and were forcibly using either thecolour.SpragueInterpolatororcolour.CubicSplineInterpolatorclasses unless aninterpolatorargument was passed. This behaviour was not desirable and was changed so that if the instantiation time interpolation class is not one ofcolour.SpragueInterpolatororcolour.CubicSplineInterpolator, then, it will be used instead and thus it will take precedence over the CIE 167:2005 recommendation. (@KelSolaar)
The immediate consequence is small numerical changes to various spectral computations, for example:

colour.modelscolour.OETF_INVERSESattribute ITU-R BT.2100 HLG key was incorrectly named ITU-R BT.2100 HLD. (@jchwei)colour.HSL_to_RGBdefinition output was incorrect when saturation was equal to 1. (@KelSolaar, @nadersadoughi)
colour.plotting- The
colour.plotting.diagrams.plot_chromaticity_diagramdefinition was not passing anymore the CMFS to the underlyingcolour.plotting.diagrams.plot_spectral_locusandcolour.plotting.diagrams.plot_chromaticity_diagram_coloursdefinitions. (@KelSolaar, @sobotka)
colour.utilities- โ The
colour.utilities.filter_warningsdefinition was not behaving properly and has been fixed. (@KelSolaar)

Colour 0.3.15 - Alpha Milestone
๐ Features
colour.colorimetryThe 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_sdsdefinition that converts given spectral and multi-spectral distributions to multi-spectral distributions. (@KelSolaar)colour.models- Implement support for Display P3 RGB colourspace as per https://developer.apple.com/documentation/coregraphics/cgcolorspace/1408916-displayp3#discussion. (@sobotka)
- Add
colour.models.Jab_to_JChandcolour.models.JCh_to_Jabdefinitions. (@KelSolaar)
colour.plottingImporting
colouris enough to be able to plot in-place of importingcolour.plotting: (@KelSolaar)>>> import colour>>> colour.plotting.plot_image<function plot_image at 0x11e6e47a0>
colour.quality- Support for the Academy Spectral Similarity Index (SSI) has been implemented with the
colour.spectral_similarity_indexdefinition.
๐ Fixes
colourVarious fixes have been implemented to ensure compatibility with Python 3.8 and Numpy 1.18. (@KelSolaar, @MaxSchambach, @mzszym)
๐ Class methods were missing documentation as a consequence of adopting the new documentation build process, this has been addressed accordingly.
colour.io- Prevent spi3d LUT index duplicates because of floating point precision related issues. (@KelSolaar, @sobotka, @nick-shaw)
colour.notation- Fix incorrect Domain-Range scale in Munsell Renotation System implementation. (@KelSolaar)
colour.temperaturecolour.temperature.CCT_to_uv_Krystek1985definition was incorrectly implemented. Incorrect reading of the reference publications ended up with exponentiations being different, e.g.10**4was replaced with10e4. (@OlliNiemitalo)
๐ Changes
colour.algebracolour.algebra.cartesian_to_sphericalandcolour.algebra.spherical_to_cartesianuse ISO conversion convention. ฯ is in range [0, +inf], ฮธ is in range [0, pi] radians, i.e. [0, 180] degrees, and ฯ is in range [-pi, pi] radians, i.e. [-180, 180] degrees.
