hair colours and cuts

The more i look at different blonde shades. the more i am sure i want to bring out my warm red tones more. I already feel like my hair is too light (and in places almost white!) but i have been unhappy with results before because its almost looked like its just big sections of a bright copper rather than trying to keep it as natural looking as possible. If that makes any sense??!! I recently had a guy comment that im white and i have no colour and i think that was the nail in the coffin .... i want some colour and luciousness back :) As far as the cut is concerned i think it's pretty much okay as far as long hair goes?
