What colors would you have in mind? I’mt not saying -everything- in gray. I’ think it’d be nice to have thinks like accents and furniture cushions and such in other colors… Blues and greens have been proven to be the more calming, centering colors to use psychologically. Yellow has a “Happy” effect as well as being used for caution, and of course red is the color of passion and aggression, and -extreme- caution as well. Lighter beige or cream colors might not be so bad, but feel too “homey” for a military vessel in my opinion.
