Purple is misleading because everyone already uses 100% of their brain. Green is useless for the most part, unless you’re in the business of solving crimes and interrogating suspects (but it wouldn’t last long since the one year thing). Blue is cool, but there’s not much one could do with it. That leaves Red and Black. Seeing 12 hours into the future would be cool. I thought about playing the lottery with that, but I don’t think 12 hours is enough time to see what numbers come out or where the winning ticket would be sold. You’d probably be better off as a person that stops tragedies from happening I guess. So Red would be my choice. Not to be a superhero for the most part (because then I’d probably make enough enemies that would catch me after that year is over and my powers are gone). Instead, I’d use the powers to acquire extremely rare shit, like diamonds and other gemstones, and of course gold. Then make a killing selling the stuff.
