In my early collecting days, I bought both white metals (SS, WG & PT) and colored metals (YG & RG). Over time, I realized that I wore white metals much more, not because I didn't like the RG or YG, but mainly because they did not match my outfits so much. My clothes are generally in black, white or grey, so somehow only white metals suits me best. Nowadays, I only buy white metals because of this.
