Here is a script with 3 functions to find color space attributes:
- find_all_color_space_attributes: get a list of all color space attributes, in all project objects.
- find_undefined_color_space_attributes: get a list of all color space attributes with invalid color space, in all project objects. This one is particularly useful to find attributes that are using an invalid color space and that need to be fixed after changing the OCIO configuration.
- find_matching_color_space_attributes: get a list of all color space attributes that use a specific (existing) color space, in all project objects.
I hope you find it useful!
