prismatica 0.3.1

//! Egui framework integration.
//!
//! Provides bidirectional conversion between [`Color`](crate::Color) and [`egui::Color32`].
//!
//! # Examples
//!
//! ```ignore
//! use prismatica::crameri::BATLOW;
//!
//! let color = BATLOW.eval(0.5);
//! let c32: egui::Color32 = color.into();
//! let back: prismatica::Color = c32.into();
//! assert_eq!(color, back);
//! ```
