What would look best, hair question?!?

Should i :

A: dye it all light brown, and get lots of platinum highlights(thinner so can still see brown)

OR

B: just add platinum highlights and brown lowlights?

THANKS!! ( ill add a pic but i dont have one of the color it is now, but maybe it will help?)
