This would be the best one..it`s the deepest shade.... your system is one step up from a 1b ....this product is best used from day one in the life of a system as a colour -maintainer....it`s not as effective once fading has set in in earnest [in my own experience] --- it will work, but you may notice the colour ` lifting` again in a relatively short time-frame but by all means don`t let me put you off getting it.....just that it`s more effective if used from day 1 !
