iOS dark mode renders user prompt bubbles light with dark text when accent color is Black
Summary
On the ChatGPT iOS app, Dark appearance + Black accent color renders the user's prompt bubble as a light gray/white rounded rectangle with dark text instead of a dark bubble with light text.
This makes prompts substantially harder to read for users who rely on a dark UI.
Environment
- ChatGPT iOS app: 1.2026.202 (build 30140022279)
- iOS: 27.0
- Appearance: Dark
- Accent Color: Black
Steps to reproduce
- Open ChatGPT on iOS.
- Set Appearance to Dark.
- Set Accent Color to Black.
- Open a conversation and send a prompt.
Actual behavior
The conversation background is black/dark, but the user's prompt bubble is light gray/white with dark text.
Expected behavior
With Dark appearance and Black accent selected, the user prompt bubble should remain dark/black with high-contrast light text, or there should be a separate control for prompt-bubble background/text colors.
Accessibility / usability impact
The light prompt bubble is visually jarring in Dark Mode and can reduce readability for users who specifically need white text on a dark background.
Additional context
Switching among the exposed appearance/accent settings does not provide a way to force a dark user-message bubble independently. A screenshot from the affected device shows the dark conversation background with the user prompt rendered as a light bubble.
