The Unattainable Raspberry

So at the moment my hair is cerise over bleached hair. The ends are a little darker than the roots as they bleached to a darker shade due to past colourings. I'm thinking I just need to add in a tiny bit of another colour to bring it from being a bright pink to being more of a raspberry shade the next time I dye, but I don't know what that colour would be! The last thing I want is any sort of orange fade, I don't mind if it fades to pink but orange bases begin to do my head in! The colour I'm after is that famous photoshopped picture of the girl with the ponytail, I'm sure most of you will have seen the one im on about, im pretty sure it's been posted on here quite a bit. Any advice on how to go about it? x
