If you dye your hair at home, try Clairol Nice & Easy Perfect 10 hair color. It is the best, easiest color I have ever used, and it looks fantastic. I'm about a 3.5 neutral brown, with a some grey, and I use 4R— a gorgeous dark auburn that looks incredibly natural, has great highlights, lasts a long time, and fades beautifully. It doesn't ever get brassy or orange. And the added benefit is you don't have to do your outgrowth separately, because it's only on your hair for 10 minutes. I was really worried I would get hot roots, but nope...it really is perfect. Plus it has this awesome comb tip applicator.
Even my hair stylist won't touch my color because she says she can't do a better job. She actually recommended this one to me when I was trying to figure out how to dye my hair after I cut it into a pixie. It's really hard to do outgrowth when your hair is really short. I was already using the same pigment with a different developer and she said in her delightful Bulgarian accent "Darlink, when you find what works, you stick with it."\
TL/DR: Pretty hair!
