I have used americolor fuchsia to get that color, first I tried mixing it but never succeeded… According to the charts it should be purple and red mixed but it never looked good so I just bought it. You could even try Americolor Electric Purple but that one is a bit more dark than fuchsia. Hope this helps :)
ps. I took a photo of both of them, maybe this will help you to see how they look before you decide if they are the right ones :)
