60-40 mix of Manic Panic Electric Lava and Pillarbox Red with just about a quarter sized amount of Ultra Violet in the front. The back is Pillarbox Red over faded Raven.
Did just the front mainly because I didn't have enough bleach for the whole head and partly as a test to see how it would look. I haven't done red since 2006, and that was a very dark red. I kind of like the two-tone look though.
As I remember from years ago my hair doesn't like to bleach. Took a total of 4 hours with 30 vol bleach to get it to that golden orange shade and I didn't bother going any lighter because I wanted orangey red to begin with.
