I've coloured my natural mid brown hair using directions dark tulip. It's not the colour I was looking for. I wanted it much darker. Can I mix directions ebony with dark tulip to make it darker or will it look muddy?
it will depend on the base of the black. if it is red based then you can use it. if it is green, it will get muddy. I can't remember what base it has as it changed a few years back.
I think you'd be better off using Plum so it's in the same colour family.
Edit - Though it depends on the result you want. If you're happy for it to go a little more to the red side and lose some of the blue, use a red based black. If you want to keep the purple tone use Plum. If you're happy with it going more brown/burgandy if you're lucky, use a green based black as that will tone out the pink quite a bit.
I *think* directions ebony is red based now.
