For my taste form and function have to fit and if they do the object, be it a handgun, a car, a light switch or a chair back, has a natural aesthetic beauty. I dislike carving on wooden furniture and pin-striping on cars.
I prefer my guns plain vanilla too; I dislike gaudiness and consider it vulgar. Thus my semi-autos are almost all black all over, or the darkest color offered. I don't need or want them to be pink or purple with a rose engraved on the slide, so they're not. Two-tone silver and black combinations usually look to me like something a pimp would carry. At no point before I fire would I want to draw unavoidable attention to a gun I was carrying.
I have two Ruger revolvers, GP100 and SP101, that are stainless steel with black grips. I was told that stainless steel would survive better if exposed to the elements, and these are my potential hiking guns. I don't consider them gaudy, but the do catch the eye.
Wait, I think I have some lint in my belly button...
