Why these colours?
Calculated blackbody colour at 5,231 K
The colour a perfect blackbody at 5,231 K would have, calculated with the CIE 1931 2° observer and shown as chromaticity only, so the brightest channel is full. A real star’s spectrum has absorption lines and is not a perfect blackbody, so this is a model, not a photograph.
From: Calculated blackbody colour at 5,231 K Calculated visible-colour model
Colour clusters describe pixels in an image; they cannot identify a mineral, a gas or a physical temperature. Shares of pixels describe the sampled region of the image, not the object’s surface.
Colours from selected views
Palettes sampled from identified images and regions, or calculated from a documented model. These values describe each image or model, not one permanent colour of Alpha Centauri B.

Schematic sphere A plain sphere tinted with the anchor colour of the named view; it shows no surface detail and no measured shape. Objects are enlarged or scaled for inspection unless stated otherwise.
Use these colours
Every palette above opens in the palette generator. With JavaScript you can also add colours to your cosmic palette, save them, make a gradient or pattern, preview them in a design or a room (you choose which colour goes on which surface), check digital accessibility and export them. Each colour keeps the view and sample it came from.
Paint matches compare digital swatches for design inspiration. They are not physical equivalents of light from space. Edits create a new design palette. The original representation remains unchanged.
