Survey references for how other systems model color pipelines.

[reinecke]

We should look at what people are currently doing to model color existing DCCs and their pipelines and assess strengths/weaknesses of these approaches.

Examples from USD:

• USD Attribute Color Space API
• USD stage Color Configuration API (you need to search Color Configuration API in that page)

OCIO colorspace Modeling:

• colorspaces

MP4/QuickTime:

• Colorspace is defined in the colr box which provides for a colour_type specifying restricted ICC profile, unrestricted ICC profile, or a collection of colour_primaries, transfer_characteristics, matrix_coefficients, and a full_range_flag
