Go (golang)
Go language brand palette captured verbatim from the Go Brand Book v1.0. The brand is led by Gopher Blue (#00ADD8) and supported by Light Blue (#5DC9E2) and Fuchsia (#CE3262). Secondary swatches add Aqua (#00A29C), Black, and Yellow (#FDDD00). "More colors" sit below as supporting tones (Dark Blue #00758D, Cool Gray #555759, Plum #402B56, Light Gray #DBD9D6). Black is documented as the high-contrast foundation.

- Hex values resolved from the Go Brand Book v1.0 PDF (go.dev/s/ brandbook), page 16. The dark-mode role mapping is brand-atoms' sensible inversion (Black canvas, Gopher Blue identity preserved); the Brand Book is light-first and does not enumerate a dark mode but explicitly designates Black as the "high-contrast foundation."
