color: set initial default value for 'colormode' to None
This should not introduce any behavior changes when using the color extension.
In practive, the colormode will be setup at early at run time to the proper
value (from config and environment).
We do this change as this gets us closer of a state were we can have all the
mechanisms associated to color in core with the feature disabled by default.
