I'm sure Komatsu has an "official" color. All manufacturers do (and usually copyrighted). Can't really go by photos on the web. What was the lighting like when the photo was taken? What were the camera settings? Was the photo edited? Was the photo just a quick snapshot or taken by a pro? If you have to go by a photograph I'd look at a Komatsu dealer's web site. Your monitor is calibrated isn't it? Best is to just go look at one in the wild if at all possible, or get a can of touch-up paint from a dealer. I agree with everyone else too, that's one good looking machine you've built.
