Bo Katan Bo katan colors , especially helmet

I am in the middle of building my daughters Bo Katan, and am a little confuses with no CRL to confirm what will be approved ;-) so looking for input from the masses.
I used a med blue on the main helmet, obviously a white front and gray on the raised rear rim, but i'm seeing a lot of people using blue. will post up pics as soon as I switch to my phone. Any thoughts. The second 2 pics are what i'm referencing to conclude a gray is correct.

the grey is correct just as you did color your helmet good work!

CRL's for Bo can be found at The Bounty Hunters Guild. The helmet should have the same dark blue on the back lip as is used in the front cheeks shading. Only grey on the helmet is the RF Stalk and the back key slot area.
