+//! # Color
+//!
+//! The `color` crate provides a set utilities for working with colors. It is a wrapper around the [`palette`](https://docs.rs/palette) crate with some additional functionality.
+//!
+//! It is used to create a manipulate colors when building themes.
+//!
+//! === In development note ===
+//!
+//! This crate is meant to sit between gpui and the theme/ui for all the color related stuff.
+//!
+//! It could be folded into gpui, ui or theme potentially but for now we'll continue
+//! to develop it in isolation.
+//!
+//! Once we have a good idea of the needs of the theme system and color in gpui in general I see 3 paths:
+//! 1. Use `palette` (or another color library) directly in gpui and everywhere else, rather than rolling our own color system.
+//! 2. Keep this crate as a thin wrapper around `palette` and use it everywhere except gpui, and convert to gpui's color system when needed.
+//! 3. Build the needed functionality into gpui and keep using its color system everywhere.
+//!
+//! I'm leaning towards 2 in the short term and 1 in the long term, but we'll need to discuss it more.
+//!
+//! === End development note ===
