What color did Carrie Bradshaw dye her hair?

If you are talking about the multi color of browns and blondes, here it is.

there are 4 colors....neutral medium brown, light red brown, light blonde and dark blonde.

part the hair in three sections using a zig zigging part. the crown is one, the middle two, then the thrid is from the lwer back ear to the nape. section 3 you color in the red brown. foil it off to prevent bleeding into the next section. section two, color the roots the neutral brown, and using foils, alternate the midshaft to end in the light and dark blondes, adding more light blonde near the front,

the top section, apply the neutral brown to the roots to halfway down the midshaft, going down a bit further hen you did in section two, then alternating foils again, apply the light and dark blondes from the lower midshaft to the ends, meshing a bit of the color with the bottom of the neutral brown to get the uneven grown out look.
