Both colours are modelled predictions, not photographs. The full-spectrum swatch is our most complete model; the Roman view is coarser (four bands). This planet's light has never been isolated by any telescope.

Render fidelity + style are on the scope controls below. Spectrum engine: PICASO radiative transfer. Model assumptions — cloud state: warm, partial cloud / haze; metallicity: 1.0× solar; phase angle: 0°.
