There's already printing on the pick guards and neck of the electric guitars. If you're referring to the acoustic guitars, it would be a good idea for the necks (like a black acoustic with a reddish brown printed neck), but impractical for pick guards unfortunately because BF acoustic guitars lack a pick guard detail.

I'd like to see maverick hair in dark tan so that i might chop down the back and update this guy:http://www.brickshelf.com/gallery/bogey175/RE/rlauncher.jpg

Hey Brickforge,
I absolutely love the new items. The hairs, guns, tools, instruments... this is probably my favorite mold to date, simply given the quality and variety. A few items I'd love in new colors:
Purple Coilguns: This unique piece looks part Marathon, part District 9 and all awesome. In purple, it would make a fantastic piece of 'alien weaponry' for the Space Marines to wield.
Light Blue Battle Shields: In the new trans-light blue colour, I think the Battle Shield would serve for an energy field, perfect for Halo aliens and elven warriors alike.
Dark Tan Hair: You can never have too many hairs in too many colors, as proven by my bulging stash of custom and offical do's. The new Mohawk, Ponytail and Maverick hair could definitely prove useful to many in a dusty makeover. Any other colors for these coifs would be greatly appreciated, too!
Thanks for hearing me out, and keep up the good work, BF Team!

It would be nice to have some Chrome weapons, like BF puts on their Chrome Headgear Minniquins.

The Acoustic Guitar in black would be nice.

I second the light blue battle shield and dark tan hair that Nermal suggested.

Lego used a mix of black and silver in the lego vikings sets for helmets and axe heads since those sets the colour has been used alot by lego and i would love to see some BF armor and weapons to match those lego products

I think that speckled color would be too hard to do. Maybe a marbled color?

It couldnt be as hard as chroming the helmets, they could do them occasionally like chrome items.

i see what you mean, it would be easier but i dont know if it would match the lego colour well enough

Black Speckled is painted on rather than molded I believe. I don't see this coming about. Marbled colored might be very interesting if BF can do that, but it'd have to be for the right accessories. I'd like to add my vote for Trans-Yellow and Trans-Black again.

Regarding how successfull was the "UN-light blue" with the "Military Helmet", I thought it would be a good idea to make it available for the new "Soldier Helmet". As it looks a bit like the helmets used by UN forces in many countries (look at the last pictures about Ivory Coast).
