# colorchoice > Global override of color control [![Documentation](https://img.shields.io/badge/docs-master-blue.svg)][Documentation] ![License](https://img.shields.io/crates/l/colorchoice.svg) [![Crates Status](https://img.shields.io/crates/v/colorchoice.svg)](https://crates.io/crates/colorchoice) ## License Licensed under either of * Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or ) * MIT license ([LICENSE-MIT](LICENSE-MIT) or ) at your option. ## [Contribute](../../CONTRIBUTING.md) Special note: to be successful, this crate **cannot** break compatibility or else different crates in the hierarchy will be reading different globals. While end users can work around this, it isn't ideal. If we need a new API, we can make the old API an adapter to the new logic. Similarly, we should strive to reduce **risk** of breaking compatibility by exposing as little as possible. Anything more should be broken out into a separate crate that this crate can call into. Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual-licensed as above, without any additional terms or conditions.
