Longer lasting alternative to L'Oreal Dialight?

Could someone give me some suggestions please?  My mid length hair is bleached from about the chin down (grown out), auburn boxed colour over this which has grown out to about my ears and is natural up to the root.  Pic attached.  I coloured my hair with L'Oreal Dialight in 7.43 with 9vol developer and loved it.  It made the bleached parts copper and put a copper sheen on the rest of my hair.  Only problem was it only really lasted 2-3 washes.  Is there another range that would give me this effect but would last longer?  I'd prefer to stick with a semi but would consider a permanent. Thanks for any help.
