I have naturally dark brown hair (probably level 4 or 5 depending on time of year). I lightened it up just a bit to about a (coppery) level 6 or 7, mixed about 1:1 virgin pink and purple AF (with just a tiny dollop of wrath for fun) and ended up with the most perfect violet red color! In some light it reads more purple, in sunlight it leans red but I'm really loving how vibrant it is.
