0001 # psyfiTestingConfig
0002
0003 ## What it Is
0004 This is a simple Blender OpenColorIO configuration and LUT / matrix set that is useful for testing color management.
0005
0006 ## What it Does
0007 Traditionally, Blender assumes sRGB primaries for input and output. However, some areas remain without color management that form critical pinch points where the primaries or transfer curve cannot be correctly displayed. This configuration shifts simply rotates the sRGB primaries to make it extremely clear where color management is not working.
0008
0009 ## Usage
0010 Within your Blender build or install, move the ```<BLENDER_HOME>/bin/<VERSION.NUMBER>/datafiles/colormanagement``` directory to an alternate name to preserve it. Symbolically link this repository in its place.
0011
0012 ## Testing
0013 The repository includes a marcie-whacked.exr image that has data values with strongly shifted primaries. There is a default transform that corrects this for pure D65 sRGB output.

0015 ## Examples of Current Color Management Breaking Points
0016
0017 ### Color Wheel
0018 Currently the color wheel is not correctly displayed. It is impossible to display sRGB on a display, as the color wheel is not hooked into the color management system and cannot be adapted for the intensity / transfer curve and primaries of the display. This is especially noticeable on wide gamut displays.
0019
0020 #### Color Wheel Testing
0021 Change to a paint mode and try painting on the sample image. The colors selected in the wheel will not match the working space.
0022
0023 ### Eye Dropper Tool
0024 The eye dropper does not currently convert the sampled working space values to a corrected display output.
0025
0026 #### Eye Dropper Testing
0027 Change to the eye dropper and select an area from the sample image. The results will be displayed untransformed to the artist.
0028
0029 ### Multiple Monitor Configurations
0030 Due to the Blender only having a single output display transform, it is impossible to properly display color on multiple head systems. Instead, only one can be properly corrected and hook a profile into the system.
0031
0032 #### Multiple Monitor Testing
0033 Currently unable to demonstrate this shortcoming using this repository. Only a single output transform can be defined, and as such, multiple displays cannot have their profiled adjustments included into the system.
