hair help

has anyone used the wella toners for blonde hair? I had used them years ago but at the time I didn't know much about toners so I dont think I did it right plus I'm thinking I got the wrong color for what I needed back then. now that I know more about how to use them I'm thinking of trying them again but just want peoples experience and how well the color came out as well as what ones you used. was it pretty true to the color or does it come out darker than what is shown. my hair is already lightened I just need it toned.
