I've checked in logging level change but will leave this bug open as further work is needed to verify the function processing issue.

The warning error in this can be ignored as the colour space has fallback code to get the colour from an alternate colour space. We are seeing no colour space issues with the rendered output. We could move the logging level to finest to avoid any customer concerns.
