K.F.
K., the best colorist I've ever known is Christy Harris, who works at the salon Personalities in Manchester (in the Gold's Gym shopping center at Weidman and Manchester). Their number is ###-###-####. When I started having mine colored instead of doing my own, she was able to perfectly match the color, and highlight beautifully. She also was phenomenal when I wanted to play with slight changes in shade. I can't recommend her highly enough!
Good luck!
