Feature request: color customization for custom slash commands

Feature Request

Summary: Allow users to visually distinguish between global and project-level custom slash commands through color customization in the Claude Code UI.

Problem

When using a mix of global (~/.claude/commands/) and project-level (.claude/commands/) custom slash commands, there is no visual distinction between them in the slash command menu. This makes it harder to quickly identify the scope of a command at a glance.

Proposed Solution

Support color or visual differentiation for custom commands, for example:

• Different default colors for global vs project-scoped commands
• A configurable color property in command/skill frontmatter (e.g., color: blue)
• Color-coded icons or badges indicating command scope

Any of these approaches would improve the UX when working with many custom commands across different scopes.

Workaround

Currently the only option is to use naming conventions (e.g., prefixing with g- or p-), which is functional but not as ergonomic as visual differentiation.
