Color managed items
- UI color values
- All DCC apps provide a color-managed color picker that will return a color in the rendering colorspace. RenderMan simply uses them as-is.
- Lights
- Color Temperature was computed in Rec.709 before 24.0 and is now color-managed.
- PxrEnvDayLight is also color-managed and relies on the srgb_linear role.
- Textures
- Textures MUST be converted to the rendering color space before usage. This task can be accomplished by the Texture Manager.
- It is also possible to use the PxrColorSpace pattern to convert a texture color, but at a performance cost.
- Patterns
- PxrBlackBody is color-managed.
- PxrHairColor is color-managed.
- PxrColorSpace allows artists to convert from one color space to the rendering space.
