Neuroimaging color palettes and helpers

Lightweight, perceptually-uniform color tools with safe fallbacks.

Usage

resolve_cmap(name = "grays", n = 256)

Arguments

name

Palette name (e.g., "grays", "viridis", "inferno", "magma", "plasma", "turbo", "cividis", "coldhot", "blue-red", "coolwarm"). Any palette in grDevices::hcl.pals() (e.g. "RdBu", "Spectral", "Reds") is also accepted. Case- and punctuation-insensitive. Unknown names emit a warning and fall back to a viridis-like ramp. If you pass a vector of colors, it's returned unchanged.

n

Number of colors to generate.

Value

A character vector of hex colors.
