Colour change from dark brown to red, advice needed please!

Hi geeks,

After some advice, currently using Koleston 5/77 & 66/0 with 6% so hair is pretty dark, hoping (lol) to achieve a vibrant red a'la Amy Childs! Have read on a few threads she has Goldwell applied, would prefer to stay with Koleston as I love it! Would a cleanse bath be required and what colours would you recommend to get this look?

Thanks!!:biggrin:
