editor: Add intelligent bracket colorization (#51580)
Closes #50210 Bracket colorization currently runs theme accents through `ensure_minimum_contrast`, which can significantly alter authored palette colors in order to satisfy a single foreground-vs-background target. In practice, that makes rainbow brackets drift away from the theme colors they are supposed to reflect. This PR keeps bracket colorization as a single automatic behavior, but changes how the palette is derived: - preserve authored accent colors when they already work - adjust only the specific accents that are too weak against the editor background - only reorder the palette when adjacent bracket levels are still too similar after that The implementation is staged because bracket colorization has to handle two separate problems: - **Bracket-vs-Background Readability**: is an individual bracket visible against the editor background? - **Adjacent Bracket Separation**: can you still distinguish one nesting level from the next? Those two constraints are also why the implementation cannot simply defer to whatever accent colors the theme provides. Some themes, including the bundled One and Ayu, do not define explicit accents at all, so bracket colorization falls back to Zed's shared default accent palette. That palette was not designed with any particular theme's background in mind, which makes the background contrast check especially important for those cases. That is why the previous `ensure_minimum_contrast(..., 55.0)` path is not enough on its own. It addresses foreground-vs-background readability, but if lightness-only adjustment cannot satisfy that target it escalates to saturation reduction and then black/white fallback. This PR instead keeps the bracket-specific background fix bounded and lightness-only in OKLCH, so the resulting color stays much closer to the authored accent. ### How it works - **Background Contrast Correction**: accents that fall below the APCA floor against the editor background are adjusted by changing OKLCH lightness only, preserving hue and chroma - **Adjacency Correction**: if the resulting palette is still too weak between neighboring nesting levels, the palette is reordered conservatively to improve adjacent separation That ordering matters. Doing the reorder first can easily be undone by the background-fix step. ### Color measurement - background contrast uses APCA, via the existing `apca_contrast` path - adjacent bracket separation uses OKLab Euclidean distance APCA is the right tool for bracket-vs-background readability, but it is not designed to compare two foreground colors against each other. OKLab distance is a better fit for detecting when neighboring bracket levels are perceptually too close. ### Thresholds - background APCA floor: `30` on dark themes, `35` on light themes - adjacent OKLab target: `0.08` on dark themes, `0.10` on light themes - light-theme reorder tolerance band: reorder only triggers below `0.095`, avoiding threshold-artifact reordering on palettes that are visually fine but narrowly miss `0.10` ### Validation - `cargo test -p editor bracket_colorization` - manual comparison on bundled One, Ayu, and Gruvbox theme families Release Notes: - Improved bracket colorization by preserving theme accent colors when possible and applying targeted contrast fixes only when needed. --------- Co-authored-by: Kirill Bulatov <kirill@zed.dev>
