Description

As of the 1.0 release, the UI is unusable in a terminal that does not support truecolor. Based on my testing, this appears to be the case for all color themes.

OpenCode version

1.0.7

Steps to reproduce

  1. Use a terminal that doesn't support truecolor (such as Terminal.app on MacOS 15.6 Sequoia)
  2. Run Opencode 1.0+

This issue might be a duplicate of existing issues. Please check:

  • #101: Discusses using terminal theme colors by default instead of hex colors, which would solve truecolor compatibility issues
  • #3644: Feature request for a 'system' theme that uses existing terminal palette, which is exactly what would fix this issue
  • #19: Technical implementation request for custom themes using 0-255 terminal color codes instead of hex colors

Feel free to ignore if none of these address your specific case.

Providing a 256-color or ANSI compatible theme could potentially be a workaround, which in the case of the latter could simultaneously solve #101 and #3644.
