Colour is not only aesthetic. It is interpretive bias.
Different wavelengths of light influence contrast perception and depth cues. They alter figure-ground relationships.
When I worked with sustained colour exposure, sitting with red, or blue, or green fields, I observed shifts in internal narrative tone.
Red intensified boundary awareness. Blue softened edge perception. Green often stabilised breath rhythm.
These observations are subjective, but they are consistent.
If perception is predictive, colour changes the priors.
It subtly shifts the brain’s expectations.
We often treat mood as internal and autonomous.
But interpretation is modulated by sensory context.
Change the light. Interpretation shifts.
That does not mean colour controls emotion.
It means perception is relational.
