I think the main reason certain companies are coming out with these less than traditional color designs is to target the ever growing market of women who buy firearms. More often than not women tend to gravitate towards what guns look cute, hence the reasons for all these companies coming out with pink firearms along with pink accessories like grips, ar stocks, uppers and etc.... Go to Sig's website and look at all the color variations of the p238. To the traditional shooter they may look horrifying, but to certain women or younger shooters they may have that neato factor.
Although I consider myself a traditionalist I do think the kel-tec P11 with stainless slide and navy blue frame looks pretty sleek
