I gotten pretty good at choosing my colours over the past couple years, so I think there's only a light green Tern I still bag which can be tough to find. To my credit, it looked more like a bright yellow in the photo when I bought it. Great flier though, so it'll stay until I lose it.
Otherwise I do putt with a Black Reko. Although it'll be tough to loose a putting putter, I have had a few moments.... I switch to my white Reko when It gets darker.
