I look at the colors & think of the original Lightweights,, which have become collectable in general. There are the Tri-Colored ones, as well as the blued ones. ALL are sought after by those of us who collect.
The Wranglers,, are as noted,, a beginners gun,, albeit a quality built beginners gun,, AT AN AFFORDABLE price for many who are not (yet) serious gun folks. AND they also are a fun plinker for those of us who want a gun we don't have to worry about banging around. Are they a serious hunting gun? No. Are they the best choice for SD? No. Are they good for introducing children to shooting? Yes. Are they good for getting folks a gun on a limited budget? Yes. Are they good for getting folks to enjoy a SA design? Yes.
I agree that many folks may not find them to their liking. But I also look beyond my own preferences,, and see the potential for many other people.
And hey,, if it gets someone interested in SA guns,, where they craze has been semi-auto, black & plastic,, then it's a GOOD thing!
