NO MORE RED TONES PLEEESE!!

I was told that I naturally have red tones in my hair already, but don't want red tones to show. My hair is dark brown naturally and everytime I dye it any light brown, it always ends up orangy.

If I use an ash brown, will it work ok? But I also have highlights, but they are a little golden themselves. How will the ash come out on the highlights, even though they are golden too, but is still blonde?

Most dyes come with 20 v developer thats able to lift one or two levels. Because you have dark hair( level 2 or 3), you are not going to be able to achieve light brown( level 6) with 20 v, I doubt any volume of peroxide will be able to lift you to light brown.

Your probably going to have to bleach to orange stage and then tint with a neutral level 6 or an ash 6. I would not pull the color through, just bleach and tint the roots.
