Problem statement

Claude Code on the command-line (VS Code) will not respect custom colors for agents.

The WP-CLI agent is running with the #0b0033 color configured in its definition file. The

visual color will display in the Claude Code UI (web, desktop, or IDE). If you're viewing this
in Claude Code and the color still isn't showing as the dark purple #0b0033, it may require a
refresh or there could be a caching issue with your Claude Code instance.

Add custom colors for agents. It's nice that there are colors to choose from, but teams and individuals could benefit from being able to match branding to their own colors.

Proposed Solution

Allow defining custom colors for agents, IE:

model: haiku                                                                                                                                                  
color: "#0b0033"

custom color:

Potential pitfalls

Developers would need to customize their environment for good contrast of custom colors.

Alternative Solutions

Open in Claude Desktop app or web interface (I never use these.)

Low - Nice to have

Configuration and settings

Use case

For example, let's say I have an agent that does things in a normal way:

• code: green
• review: yellow
• bugfix: red

These may even match tags in GitHub. But let's say I have a proprietary solution, and I want to see how often my agent is invoked by changing the color to my personal brand: #0b0033

Closing Claude Code CLI, and re-opening, strips the color:
