             Summary: camel-jbang - TUI shell panel: command echo and error output render in hard-to-read dark red
                 Key: CAMEL-23830
                 URL: https://issues.apache.org/jira/browse/CAMEL-23830
             Project: Camel
          Issue Type: Bug
          Components: camel-jbang
            Reporter: Adriano Machado


In the embedded
  shell panel \(camel\-jbang TUI, ShellPanel\), text echoed while typing a command, and error output such as "Unknown command: x", render in a dark red \(\~RGB 136,0,0\) that is hard
  to read on dark terminal themes. The prompt itself renders fine \(camel in orange, version in green, > in white\).

Root cause: JLine command highlighting colors unrecognized
  commands with ANSI red \(index 1\), and JLine ScreenTerminal encodes named ANSI colors as a 4\-bit\-per\-channel RGB value. ShellPanel.convertAttrToStyle reconstructs that as a
  literal dim RGB instead of a terminal\-themed named color. Elsewhere \(TuiHelper\) the TUI uses Color.ansi\(AnsiColor.RED\) so the host terminal applies its theme and stays
  readable.

Acceptance: command echo and shell error output are legible on dark and light terminal themes, consistent with how other TUI components render ANSI
  colors.
