Problem or use case
I'm red-green colorblind, and the diff panel is basically unusable for me. The red/green coloring for additions and deletions blends together, so I can't tell what was added vs. removed without reading each line carefully.
Proposed solution
Add a "Colorblind-friendly diff colors" toggle in Settings > General that swaps the diff panel palette from red/green to blue/orange.
Blue and orange are distinguishable across all common forms of color vision deficiency, including deuteranopia, protanopia, and tritanopia.
Why this matters
About 8% of males have some form of red-green color blindness. Anyone in that group currently can't use the diff panel effectively.
A simple opt-in toggle fixes it with no impact on anyone else.
Smallest useful scope
A single boolean client setting that swaps the CSS color variables on the diff panel.
Four files, roughly 60 lines.
Alternatives considered
Custom themes (#1279) would technically solve this too, but that's a much bigger scope.
A focused toggle is simpler, ships faster, and directly targets the accessibility problem.
Risks or tradeoffs
None significant.
It's opt-in, default-off, client-side only, and uses hardcoded OKLCH values that don't depend on any theme variables.
Examples or references
