// mood_palette.h - turn the room's mood into a colour family.
//
// Warmth (from valence) picks the hue centre: cool blues and teals for a
// sad or tense room, ambers and magentas for a happy one. Arousal picks how
// saturated and how wide the family is: a calm room is pastel and narrow,
// an excited one is vivid and spans more of the wheel.
