However, the OP expected the GREP_COLOR setting on the command line to override the GREP_COLORS setting in the environment, which it doesn't.
Thanks, your explanation let me see the problem.Since GREP_COLOR is deprecated, I doubt whether we should be changing grep to support this obsolescent usage in a different way. When it comes to obsolescent features, the only thing we're likely to change is to remove them entirely (as any change will disrupt somebody...).
