My favorite color was always blue, then it was orange, now I'm shifting from that to yellow. I see appealing qualities in all three but I feel like my personality and tastes have shifted over the years so I identify more strongly with one than the others.
With yellow I started wearing a lot of yellow clothing over the years as my terminal Bruins fanboyism progressed to Stage 4, and it opened my eyes to how fun a color it is to wear in general. I've also gone from wanting to blend in to wanting to stand out.
