My 1" dark blonde roots don’t look so hot

Hello, My name is Kelli and this is my first post on here. I have just one question that I would love to get a little advice about. I naturally have medium-dark blonde colored hair (a.k.a Icky looking "dirty dishwater" grayish blonde) I tried to dye  it  a light champagne color and it just turned kind of a light  orangish-yellow,and I have been died it that same orangish yellow color for about  5 months now ( I tried to change it but no other color was being taken into my hair,except for at the very ends which I think is wierd,but I am of course trying to do this all myself so who knows) Now all I want to do is somthing to make it look good while it grows out. Which would be better of these two: putting somthing like lowlights in it to blend the colors together better or dye the whole thing to a dark blonde and put highlights in it? I just want  a  managable color and looks better then my naturaly but isn't such a pain in the butt. Any responses are greatly appreciated!! Oh, I am by the way, not going to try to do it myself, I'm sure that'll bring comfort to you stylists out there!

Thank You!!
