### I thought about it too. If you redo the organization of color rosettes
in the occipital cortex you should be able to squeeze additional colors
into the perceived spectrum. You would also need to add bandwidth to the
subcortical structures and additional parallel color sensors if you wanted
the new perceived colors to correspond to specific features of the
environment. Obviously, yes, colors are concepts created by our brain to
label objects, so they are informational rather than simple physical. This
is not to say that informational means non-physical but rather
informational is complex physics that happens in computing devices compared
to simple physics that describes objects in general.
