I agree this is very beautiful color.
I have one important question though. What color was the hair BEFORE it was colored with the PC which has no lift properties whatsoever.
No you don't to use bleach if the hair is naturally light when you start (Level 8,9, 10).
However, if hair is a Level 1, 2 or 3 (very dark) many colors just won't show up without lightening the base first.
Just my very humble opinion after many years in the world of hair.
