What color to purchase if your brows are black with white brows coming in?

I am 65 now and my eyebrows have been over plucked over the years. Although my head hair color is a lovely shade of brown with more gold then red highlights (very natural looking), my eyebrows are still quite black with white brows coming in and attempting to take over. I do use my hair color on my brows, but that does not last long. Any brown brow pencil, no matter how dark, still looks brown, not black.
My skin is quite fair.
What color Le Crayon Poudre would you recommend for me?
