Three or four problems with your claims. Behavior comes from circulation, endocrine, muscular, gustatory, respiratory, and muscular information systems. Not all of those are located or controlled in the brain. In fact a substantial part of the nervous system and a substantial part of behavior is controlled, initiated, influenced outside the brain.
Behavior?
A reflex is behavior but it is controlled by inner "programming".
There is no thinking or what we would call "willing" involved.
Now if you want to go all nineteenth century about creating you may have an audience.
You can't have an arm without the creative power of evolutionary change.
The arm is a creation.
Just like the ability of a brain to create the experience of color is an evolutionary creation.
If you want to look at the sources of human creating behavior you might consider the mechanisms underlying endocrine and hormonal systems mostly governed by organs in the torso and abdominal regions and communicated with via vascular system.
A hormone like testosterone can effect behavior. But not the visual reflex.
A hormone like thyroid hormone can effect energy level and growth and temperature. But not the visual reflex.
Epinephrine and Norepinephrine directly effect the nervous system. The sympathetic and parasympathetic systems.
Dopamine and serotonin work in the brain and in the enteric nervous system.
But the visual reflex is not effected by those nervous systems.
Remember the "I ran and I was afraid or I was afraid and I ran" issues back in the day.
There are two kinds of grammar.
Natural grammar that allows even people who never went to school to talk and understand and generally use proper grammar but some there are usually mistakes in what an "educated" mind would call "proper grammar".
And there is man-made grammar. A bunch of useless rules that are arbitrary and not needed for communication but can distinguish a person as having a certain education and indoctrination.
Or how about gate pain theory.
All physical therapists are very familiar with this theory. It is the theory behind the application of 'TENS', an electrical modality applied to the skin, for chronic pain.
Some kind of gate theory might apply to the visual reflex. The application of energy in the entire spectrum wipes away the individual color experiences and white is experienced instead.
Or you might look at chemical system changing moods and/or priorities.
Without a doubt chemicals change moods. Testosterone is a classic example. When administered at certain levels people become aggressive with higher levels of anger.
They are in a sympathetic fight mode all the time. This helps with weight training and sports.
You need to keep the sympathetic system in check though. The young child that rolls on the floor and cries in anger when frustrated. They have not learned yet to keep the sympathetic system in check. This is hopefully learned before puberty where the hormones make it more difficult. But even childhood learning can be overpowered by unusually high circulating levels.
No matter. Just be assured you don't have a clue about what is and how does experience operate.
I know beyond any doubt that energy cannot pass on information to an evolving brain about what to make from the stimulation from that energy.
Abilities are gained though evolution and random changes of the brain. Not because of information passed from the environment.
There is no mechanism for EM energy to tell a brain to make orange when a bit of the 'red' and a bit of the 'green cells' are stimulated.
Finally the brain is not about tones of behavior it is primarily a machine that organizes inputs into behavioral choices for executive functions against current behavioral status and organize proper bodily responses including situational status and action options.
Memory is all about the storage of information.
The visual reflex is not about memory however. It is about immediate stimulation. If something is experienced it can become part of memory however.
Saying the brain does not have the room to contain the information necessary to create orange is preposterous.
That's like saying the spinal cord does not have enough room to contain the patellar reflex.
