Planck Ember

LITA blackbody's spectrum follows Planck's law. Its peak sits at λ = b/T, with Wien's constant b = 2.897771955 × 10⁻³ m·K (CODATA). At 2000–3000 K the peak is in the infrared (1449–966 nm), and the visible tail makes the glow orange: candle flames, tungsten filaments, embers.

MODELA forge in the void. Each ember's colour is computed from Planck's law integrated across the visible range, mapped to RGB with an approximate wavelength-to-colour table (not a full CIE colourimetry). −Orange+ is drawn as two coals: 2000 K on the minus side, 3000 K on the plus side, and their mean 2500 K at zero. Blow on the fire to heat the plus coal; let it rest and it cools.
