Coloring for semi bleached hair.

You will not get dark blonde if you just throw a box of dark blonde dye over it, you will need to lift it with more hair bleach to a shade that is more yellow to get blonde to work (boxed dyes don't usually lift very much). 

It looks light brown to me now, but your pic is very pink, so I can't see the exact shade.  If it really has a lot of orange in it, you may want an ash shade of light brown if you want to counter the orange.  If you use light brown that does not have a green or blue base, it will show more of the reddishness. 

Reddish brown will add some red, so that should show up, but no matter what you chose, I'd recommend mixing a small amount of the dye to do a test strand to make sure you like it before you do your whole head with anything.  It can be harder to remove dye if you don't like it.   Bleached hair is porous and may also come out darker than the display model, so you may want to choose a shade that is lighter than you want (since you sound like you want lighter).
