What happens when you dye virgin Indian?

I finally got my color ring in from shrinkies (I should have ordered it first, but I wanted my hair, LOL!)...anyways...I'm kinda a #5 with highlights in an #18...

I love the microwefts, and the hair is incredible...but I have them in a #6 (which is much to red for my hair, even though it blends well - just because the protac is so cool:))...anyways, they dont have them in a 5 or in an 18...

Amm - do you know how often the different colors come in?  I'm not going to need anything for another month or so...but I LOVE playing with this stuff so much, I want to play now:)

So, I was going to try the virgin indian elite remy on microweft...I love the curls it has...and naturally, I have a bit of a wave...but, do you think that it would be possible to get it to a #5 or even a #18 without making it hard to manage...could I do it myself going through a sallys?

thanks!
