Core affect
Russell’s circumplex places every mood on two scales: how pleasant it is, and how activated the body feels. “Aura color” here is that plot, made visible.
Feeling is not a colored light around the skin. In psychology it is a construction: the body reports activation, attention frames it, and the mind gives it a name. Drag the map. The glow follows core affect — pleasantness × arousal — the same two axes James Russell used to chart emotion.
Tap or drag. Right is more pleasant. Up is more activated. Color is mixed from those two dimensions, not from chakras.
Quiet pleasant
Rest-and-restore
The brain predicts the body, then feels the difference. That loop is interoception — the sense that often gets pictured as an “aura.”
The button slowly lowers arousal and mental load. It is a demonstration of how attention can recode the same body, not a treatment.

Palmer and Schloss showed music–color matches travel through emotion. Warm hues track activation; cool hues track rest. The engine uses the same logic.
Interoceptive predictive-processing models (Seth, Barrett and others) treat emotion as the brain’s best guess about inner physiology plus context — a constructed field, not a substance.
Studies of aura-vision reports (Zingrone, Alvarado) link them with absorption: a talent for inner imagery. That is a mind skill, not proof of photonic emission.
