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:
a parametric albedo model.
Model assumptions — cloud state: rocky / thin atmosphere (grey);
metallicity: 1.0× solar;
phase angle: 0°.

Full spectrum — the colour computed from the complete 380–780 nm
reflected-light model. Roman 4-band — the same light as the Roman Space
Telescope's Coronagraph would see it, through just four filters. Both are
modelled, not photographs; flipping between them shows how much of a
planet's colour survives Roman's coarse filter set.Classic — surface colour and brightness taken straight from the physics
model (cloud bands are schematic). Stylised — that same colour restyled
into warm/cool bands and turbulence for looks: prettier, not more accurate. The palette
below is identical either way — only the picture changes.
