Correcting hair coloring mishap
	
	
		My hair was getting more and more gray rapidly, I decided to color it to it's natural color Brown/Black, it said to leave on for 10 minutes or longer for more coverage.  I wanted just traces of the gray to show through, so I rinsed it at 5 minutes.  Here's the problem with the results, it completely covered all the gray and is extremely Black, no Brown tones at all, not natural either.  How can I correct this mishap?  BTW, I am a Man and used (Clairol Natural Instincts for Men).  Please help me correct this ASAP.
