I did not add `defaultValue = "true"`: picocli applies the default value of the annotation when the option is not given, over the field initializer, so it would turn the colors on in CI and drop the auto-detection of `EnvironmentHelper.isColorEnabled()`. _Claude Code on behalf of davsclaus_ -- This is an automated message from the Apache Git Service.
