Blue is a concept we learn to associate with light of a particular wavelength
(unless you are colour deficient), but that doesn't mean that blue *is* light of
a particular wavelength. Colour is a shared subjective experience, but
subjective all the same. A blind person may know about blue, but if you gave
them sight, would not be able to identify it without an example.

The sensory input just provides us with a fairly unique set of signals to
associate with other things. The implication is that an AI will need senses
similar to ours, in order to have an intelligence we can relate to. But even
then, it will not derive by itself the same concepts that we have. It could be
that intelligence as we define it is purely a subjective view of how we develop
to react to sensory input. An AI based on logic, may perform useful tasks, but
may never seem intelligent.

Anyway the difference between blue and red is that blue is a cool peaceful
colour, whereas red is a warm vibrant one.
