Colorous

github crates.io docs.rs build status

This crate provides a collection of sequential, diverging and categorical color schemes ported from d3-scale-chromatic. Each color scheme may be sampled using either a rational index i/n or a continuous float 0 ≤ t ≤ 1.

  • pub fn eval_rational(&self, i: usize, n: usize) -> Color
  • pub fn eval_continuous(&self, t: f64) -> Color
viridis

Example

let gradient = colorous::VIRIDIS;
for i in 0..100 {
    println!("{:x}", gradient.eval_rational(i, 100));
}
