prismatica 1.0.0

//! Color text using the colored crate with prismatica colormaps.
//!
//! Applies VIRIDIS-derived `colored::Color::TrueColor` values to text
//! using the `colored::Colorize` trait for styled terminal output.
//!
//! Run with: `cargo run --example colored_text --features "matplotlib,colored-integration"`
