Smokey Lavender

Hi everyone I posted this before and didnt get an exact answer although some people were really helpful i advising the first steps.

So i did a cld remover twice, i don't think its going to change anymore, and I'm trying to get any of these colors, one is a dark smokey lavender/lilac and the others a rose gold

Ive asked over maybe 50 people in regards to the purple and nobody has been able to give me an answer. after some suggestions i looked up the colors and I'm assuming i could just use pravana lavender and add black and than silver and add black bt I'm not sure and i want to be sure before i order the item. I would appreciate it so much.
the first pic is my current hair others are desired color

Thank you in advance
