In dark mode, the currently active project or chat in the left sidebar uses a highlight color that is nearly indistinguishable from the inactive background — essentially black on dark grey. It's very easy to lose track of which project is active, and to accidentally type into the wrong chat or project as a result.

Summary

In dark mode, the currently active project or chat in the left sidebar uses a highlight color that is nearly indistinguishable from the inactive background — essentially black on dark grey. It's very easy to lose track of which project is active, and to accidentally type into the wrong chat or project as a result.

Expected behavior

The active item in the sidebar should be clearly distinguishable at a glance in dark mode — ideally with a higher-contrast highlight, a colored accent (e.g. left border, pill background, or icon tint), or some other unambiguous visual treatment.

Current behavior

The selection highlight blends into the dark background. There's no color accent or border to compensate, so the only differentiator is a very subtle luminance difference that reads as black-on-dark-grey.

Impact

Working across multiple projects simultaneously (which Claude Code encourages with its multi-project sidebar), a low-contrast active state creates a real UX risk — it's easy to submit a prompt to the wrong project without noticing.

Suggested fix

  • Increase the contrast of the active highlight in dark mode
  • And/or add a colored left-border accent or tinted background to the active item
  • Consider auditing other sidebar states (hover, unread) for similar contrast issues

Environment

  • Platform: macOS
  • Mode: Dark

extent analysis

TL;DR

Increase the contrast of the active highlight in dark mode by adding a colored accent or modifying the background to improve distinguishability.

Guidance

  • Review the CSS styles applied to the active project/chat element in the sidebar to identify the current highlight color and background.
  • Consider adding a colored left-border accent or tinted background to the active item to enhance contrast.
  • Audit other sidebar states (hover, unread) for similar contrast issues to ensure a consistent user experience.
  • Test the updated styles in dark mode to verify that the active item is clearly distinguishable from inactive items.

Example

No specific code example is provided, as the issue does not include details about the existing CSS styles or HTML structure.

Notes

The suggested fix assumes that the issue is primarily related to the visual styling of the active project/chat element. However, without access to the underlying code or design specifications, it is difficult to provide a more detailed solution.

Recommendation

Apply a workaround by adding a colored accent or modifying the background of the active item to increase contrast, as this is a targeted solution that addresses the specific issue described.

FAIL-SAFE: Given the information provided, the above guidance points are safe and relevant to addressing the issue.
