What's Wrong?

After using /color <color> to set a session color (e.g. /color pink), there is no way to reset it back to the default gray. None of the following work:

• /color default → Invalid color "default"
• /color reset → Invalid color "reset"
• /color none → Invalid color "none"
• /color gray → Invalid color "gray"
• /color white → Invalid color "white"
• /color black → Invalid color "black"

The only accepted values are: red, blue, green, yellow, purple, orange, pink, cyan — but the default color (gray) is not among them.

What Should Happen?

There should be a way to reset /color back to the default. Either:

• Accept /color default, /color reset, or /color none
• Add gray to the available colors
• Running /color with no argument could reset to default (currently it just shows available colors)

Steps to Reproduce

1. Open a new Claude Code session (notice default gray accent color)
2. Run /color pink → "Session color set to: pink"
3. Try to go back to gray:

• /color gray → Invalid color "gray"
• /color default → Invalid color "default"
• /color reset → Invalid color "reset"
• /color none → Invalid color "none"

1. No way to return to the default color

Additional Information

Screenshot showing the issue:

The available colors list (red, blue, green, yellow, purple, orange, pink, cyan) does not include the default gray, making the color change a one-way operation within a session.
