What is This Base?

Seeing as there are a lot of blue type bases;
I wanted to go for something that was possibly closer to blue animals, dilute black or as it's also known, gunmetal grey. This was originally supposed to be darker, but the only way to colour it neatly ended up lighter, but not entirely unpleasant (in my opinion).
So, gunmetal was taken, but in doing this, Fullmetal was suggested and sounds great. It really is a similar colour to Alphonse Elric's armor, and in general I love Fullmetal Alchemist. Oops. So, where the base is more of a Grey than a blue, the name works better than the blue based names. Thank you everyone who suggested.

The Specifics

Base Name: Fullmetal.
I ship the Fullmetal name because it looks like Alphonse Elric's armor color #noshame -leawolf (#95147)
Nose: Blue
Genetics: Black Medium (or Dark?) Countershaded Special.

Coloured Examples

Will try to slowly work on other ages and the male version.

Obviously I don't expect my colouring skills to be the final design if accepted, it's just a visual reference.

In The End

Tell me if it's too similar to a planned or current base.
Other than that, yay or nay to Fullmetal base?
Also, please say why or why not you like this idea.
