1. I'm male. Color depends on garment. Windshirt (or other garment worn most often, in moderate conditions): green black or grey (Leave No Trace). Shell jacket: bright 'mountaineering' yellow, for emergency use.
2. No wearable electronics integrated w/ clothing, ever. I, like most long-distance backpackers, require clothing to be compressible, easy to layer on and off, with straightforward adjustments. Any wearable electronics that /would/ appeal to me in the future (GPS and thermometer/hygrometer/barometer/altimeter would be my two choices) would have to integrate into the pack harness soley, completely independent of clothing. But even those items, in more harness-compatible formats than currently available, would not be high on my list at all, and would be a very tough sell considering current battery technology (better to keep UNDER insulation in cold weather), increased susceptibility to impact damage, etc.
Best of luck in your research!
