Would be good for any color that gets brassy

However the pump system is not the greatest and the conditioner part of the product is not the most hydrating

You only very little out on each pump and it takes forever to refill

I washed it two days later and it was orangey and yellow i was super disappointed

Then i used this redken product and followed the directions for getting the pump to work right the pump works dont listen to the negative reviews about that and turned it to week 3 and left it in for about five minutes

I find with the pump you have to do as the directions say and prime each side first before use turn it all the way to the conditioner side and then all the way to the purple side and then when you get them both working you have to let the pump fully rise before you press it if you keep pressing it continuously without letting it rise first you will barely get any product out

I like that theres a dial but it is annoying to get out you have to pump it like 30 times to get the amount you need i have very long hair
