What's Wrong?

On Claude Code with a dark theme running in a light-background terminal, the question field of AskUserQuestion renders in a light foreground color against the light background and is unreadable.
Highlighting the region reveals the text is present, just color-matched to the background.

The header chip and options list render with readable contrast in the same view — they appear to have their own background/contrast handling. Only the bare question text inherits the raw theme foreground, so
it's the only element that fails when theme and terminal background are mismatched.

Switching Claude Code to a light theme via /config resolves it.

Related: #26170 (same class, opposite direction — black text on dark terminal).

What Should Happen?

The question text should render with readable contrast regardless of theme/terminal-background mismatch — either by using its own contrast-safe styling like the header chip and options, or by the theme picker
warning when the selected theme is likely mismatched with the terminal background.

Steps to Reproduce

1. Set terminal to a light background (e.g., Terminal.app default light profile).
2. Set Claude Code to dark theme via /config.
3. Have the assistant invoke any AskUserQuestion call.
4. Observe: question text is invisible without highlighting; header chip and options render normally.
