![]() Closes #33253 in a way that doesn't regress #32175 - namely, automatically adjusts the contrast between the foreground and background text in the terminal such that it's above a certain threshold. The threshold is configurable in settings, and can be set to 0 to turn off this feature and use exactly the colors the theme specifies even if they are illegible. ## One Light Theme Before <img width="220" alt="Screenshot 2025-07-07 at 6 00 47 PM" src="https://github.com/user-attachments/assets/096754a6-f79f-4fea-a86e-cb7b8ff45d60" /> (Last row is highlighted because otherwise the text is unreadable; the foreground and background are the same color.) ## One Light Theme After (This is with the new default contrast adjustment setting.) <img width="215" alt="Screenshot 2025-07-07 at 6 22 02 PM" src="https://github.com/user-attachments/assets/b082fefe-76f5-4231-b704-ff387983a3cb" /> This approach was inspired by @mitchellh's use of automatic contrast adjustment in [Ghostty](https://ghostty.org/) - thanks, Mitchell! The main difference is that we're using APCA's formula instead of WCAG for [these reasons](https://khan-tw.medium.com/wcag2-are-you-still-using-it-ui-contrast-visibility-standard-readability-contrast-f34eb73e89ee). Release Notes: - Added automatic dynamic contrast adjustment for terminal foreground and background colors |

Licensing
License information for third party dependencies must be correctly provided for CI to pass.
We use cargo-about
to automatically comply with open source licenses. If CI is failing, check the following:
- Is it showing a
no license specified
error for a crate you've created? If so, addpublish = false
under[package]
in your crate's Cargo.toml. - Is the error
failed to satisfy license requirements
for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to theaccepted
array inscript/licenses/zed-licenses.toml
. - Is
cargo-about
unable to find the license for a dependency? If so, add a clarification field at the end ofscript/licenses/zed-licenses.toml
, as specified in the cargo-about book.
