Several reasons that I have heard of...Typically cockpit colors are studied and tested to improve fatigue and ability to reduce stress where the flight crew is concerned. Regardless of color...the colors tone typically is darker than lighter due to instrument and placard markings and the potential of interior reflections on the windscreens. While the gray still used on current short haul versions (737's), the brown is used on the long haul versions. Darker colors dissipate internal heat quicker than lighter colors and with new generation electronics, more heat build up is evident in the cockpit. In short, electronic cockpits are hotter than older conventional versions so improved cooling fans help to alleviate heat build up. If you notice Russian cockpits are generally a version of turquoise as it has proven to have a "soothing effect" on the crew. This was discovered during the development of the Bear Bomber that was designed to be a long range bomber to fly to the US during the cold war. Both the Boeing gray and brown are available in various shades which may be a direct result of the different manufacturers that offer it...g
The brown doesn't really bother. I flew MD11 with grey cockpit and now 744 with brown cockpit and I don't feel any difference to be honest. The brown is just a little brighter than the grey, but apart from that I cannot really see a difference.

In response to this comment only,
Digital cockpits are much cooler then steam gauges. I can pull a DU and hold it in my hands, I could pull an analog HSI or ADI out and burn myself. Anything in the P5 panel (overhead) is cooler on NG aircraft. Center pedestal where your com. and nav. are is alot cooler now that it is digital, I mean alot cooler.
