Not sure what to do...

Hiya!
I am looking for guidance..

Several months ago, I slowly bleached my hair (with a pre-coconut oil) and applied MP's fuschia shock all over.  Fast forward a few months of crazy busyness, I haven't done anything to my hair since, so I have a few inches of roots (very ashy mid brown with scattered silver and grey), and the FS has faded to a somewhat coppery red which is significantly lighter...I'd rather not re-bleach my hair, as I am not sure of the outcome of the condition of my hair.

Now, I have a few ideas, but I am not too sure where to begin. I only have MP dyes to work with around here:

After midnight blue (preferred...or a very dark blue)
Special effects deep purple (online).
Back to Fuchsia shock
A pink or non orange based red from MP.

I'd rather not bleach the roots, however, if I need to, I will.

My skin tone is a light olive-yellowish, and I work out regularly, so staying power would be appreciated.

Also, if anyone has another colour to suggest, I am all ears...err eyes? 😉

What do you all suggest?
