When Claude Code runs inside tmux and `CLAUDE_CODE_TMUX_TRUECOLOR` is not set, it caps the range of colors it uses. That still happens exactly as before. The step that applies the cap no longer reports back a yes-or-no result after doing so.\n\n**Why**\n\nThis looks like an internal cleanup with no visible effect. If you want full color inside tmux, `CLAUDE_CODE_TMUX_TRUECOLOR` is still the setting that skips the cap.\n\n- Area: Terminal UI\n- Names: `CLAUDE_CODE_TMUX_TRUECOLOR`\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 0\/5\n- Scope: individual\n- Heads-up: no"}
