colored osc build output

Hi, is it possible to trick a local osc build into producing colored output without much fuzz? The point is, if I 'osc chroot' into the package and trigger a build manually, colored output is generated. Therefor I guess, rpmbuild ignores/avoids certain environment values (COLORTERM?) for better parsebility. For local builds of huge projects, colored output would be much nicer, since it would be easier to distinguish between warnings and errors. Cheers, Pete
