In 1704, Isaac Newton mapped the seven musical notes to the seven colours of the visible spectrum — the same proportions, the same physics. UKIYO LIVE uses the circle of fifths as its colour wheel. C is warm red-amber. Moving clockwise through the fifth intervals — G, D, A, E, B, F# — the hue rotates through the full spectrum. Every root note has a home colour.

In 1910, composer Alexander Scriabin performed his symphony Prometheus with a keyboard instrument that projected coloured light in sync with the music. He was a synesthete who heard colour in sound. UKIYO LIVE extends his system: each chord quality carries an emotional temperature. Major chords are warm. Minor chords cool and shift blue. Dominant seventh burns orange. Diminished goes near-black.

These two systems combine into a single formula. The root note sets the hue from Newton's wheel. The chord quality sets the emotional temperature from Scriabin's mapping. Extensions — 9th, 11th, 13th — add luminosity. Every colour is computed live from whatever chord is being played. The waves, the sky, the foam, the particle bursts — all derived from the harmony in real time.

UKIYO LIVE is built as four visual worlds — each one a chapter in the same journey. The wave engine is the Sea. The mountain is the Land. The plasma surface is Space — the universe before the wave arrives. The village is the destination. Each world is driven by the same engine, the same chord colour system, the same heartbeat. Nature is the theme. The soul is the destination.
