Exoplanet Palette

the colour scheme of every known exoplanet, derived from physics
Coverage

Modelling 5790 of the ~6300 known — the nearest that pass our data-completeness gate.

The colour

Computed from each planet's reflected-light spectrum ( × spectrum) via — no photographs involved.

Two views

Every planet is shown both ways: the , and what the would recover from just . For Roman's ~dozen , that view will one day be replaced by real measured data. See the target board →

Honesty

Both are predictions, not photographs.

Jargon

Words like carry a pixel-dotted underline: hover or tap any of them, anywhere on the site, for a plain-English definition.

Filter by colour
Colourfilter by colour family

Full spectrum — the colour of the planet's whole modelled reflected-light spectrum, 380–780 nm.

Seen from Roman — the same planet rebuilt from only the the formally supports (575, 730 and 825 nm). Its bluest band is 575 nm, so nothing below that is sampled at all: the model holds the reflectance flat there and the blues collapse toward grey and orange. That gap is Roman's, not the planets'.

Switching re-keys everything colour-derived — the colour filter, the brightness sort, the similar-colour sort. 62% of planets land in a different colour family between the two views.

Both are predictions, not photographs.

Curated is the order the gallery opens in: one planet of every colour family in turn, the clearest example of each first, so the opening screens hold every colour the catalogue has. Name is A–Z, for looking one up.
