ggsci

Scientific and sci-fi color palettes from the R package ggsci, packaged as static Rust data.

This first release includes static non-Gephi, non-iTerm palettes generated from upstream. Continuous seed palettes such as gsea, bs5, material, and tw3 are exposed as static color arrays only; interpolation is future work.

let palette = ggsci::palette("npg", "nrc")?;
let colors = palette.take_hex(3)?;

assert_eq!(colors, ["#E64B35", "#4DBBD5", "#00A087"]);
# Ok::<(), ggsci::Error>(())

Lookup is case-insensitive and accepts _, -, and spaces interchangeably:

let palette = ggsci::palette_by_spec("material:blue-grey")?;
assert_eq!(palette.family(), "material");
assert_eq!(palette.variant(), "blue-grey");
# Ok::<(), ggsci::Error>(())

The crate has no runtime dependencies, no feature flags, and no build script.
