how to warm up dark ash blonde?

I have dyed dark ash blonde hair. I would like to warm it up without using bleach or color stripper. I am willing to go a shade darker if needed. Would a light golden brown dye help? Any other suggestions besides bleaching/color stripping?

I am not sure if I should use permanent or semi, either is ok at this point. I will try a dark beige blonde with a strand test first.

I used a demi permanent. I picked dark golden blonde. I am dark ash blonde. It made my hair medium brown. The directions say it lasts 4-6 weeks but since my hair is dyed previously, and it went a darker color, could this be permanent?

I have to learn everything the hard way I guess. After I calmed down and thought about it, when I used  a semipermanent to go from medium brown to black, it wouldn't come out. One year later and it had not faded at all. So I knew that the demi would never come out either. I really didn't want brown hair, so I took a chance and bleached tonight. I bleached it to a straw with a slight tint of strawberry. Then I used a neutral lightest level blonde toner over it. Then I used the same same demi shade. It was a level 7 golden blonde on the 2-10 color scale, Only instead of the 15-20 minutes recommended on the directions, I left it on 10 minutes on the middle and ends and five minutes on the scalp. I have only seen it wet, I towel dried real good and I'm sleeping with a deep conditioner in all night. I hope it looks good dry too. If not, I guess I'll have to figure something else out.

I don't think golden blonde is the right color for me either. I am so confused at this point. I am hopeful, because when I shampood,I saw some of the color come out so hopefully this pattern will continue. If I stay within the same color level, will the new dye take. For example, now I'm a level 6 dark golden blonde, if I put in a level 6 dark neutral blonde, will the new dye cover the old dye? Or do I need to go darker. I was ash blonde, now golden blonde, I guess neutral blonde is the last thing to try. I've been doing stand tests before hand, and the color looks great but when I do my whole head it doesn't seem to go with the rest of me.
