Need advice on how to achieve this hair color with henna?

[castiel]

Hi guys! So I've hennaed my hair once before, about 4 months ago. I used Red Raj for 6 hours over hair that I had been dying blonde for the past 2 years or so, and haven't used any kind of color products on it since. Here is my hair as of now;


(Eek, those roots- my natural hair color is actually light brown, that really dark-looking section is a result of using the henna on the light brown, virgin parts when I was dying the rest of my blonde hair. So, yes, there's gonna be a two-tone effect going on for a while as I grow out the damaged, previously blonde bits, yaaay. ) Also, this picture was taken in front of a window when the sun was shining, so it's more vibrant looking than usual.

Anyways, on to the question. Alaina Huffman (as Abaddon on the TV show Supernatural) is my hair inspiration. Her character is actually the reason I decided to go with Henna in the first place, and I don't regret it at all because it's done wonders for my fine, damaged hair, but I'm just not currently at the color I'm striving for. Here are some pictures of my goal (keep in mind that she's a natural blonde, so she did somehow achieve this color via dyes)

So, do you guys think this (or at least something relatively similar to it) is achievable with only henna? I'm open to other dye suggestions too, I suppose, if henna alone won't cut it. Mainly, I want to stay away from the really burgundy, coca cola red type color. I want it to look natural, y'know? Should I use Henna Sooq's Red Raj again (maybe leave it on for only 3 hours this time) or will that only make it more violent cheeto orange? Thanks in advance for any advice!
