If your oil is that black, it may have thinned out to the point it can barely maintain enough oil pressure to keep the warning light from coming on at idle speed. Also check if your oil level is too low. If it's not yet ticking and clicking, drive it to your oil change and see if that fixes it. If you car has like 150K miles or more, you might go to a heavier oil like 10w/40 maybe. Then if your oil light still flickers it might be the oil pressure sender at fault. The oil filter was probably dirty too.
