Colors no longer come from the terminal's palette, whose color 0 many color themes set to a grey that is not their background. A theme sets tview's default styles and the color names used in texts, all chosen from entries 16-255 of the 256-color table so terminals without 24-bit color show them exactly. "auto" picks light or dark from the background color the terminal reports. Settable in the Config view, applied at the next start (widgets copy their colors when created). Replaces using the terminal's own background and text colors. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019reK4DUGYqDUjniWYJvwUW
