Just got the manual to study for my driver's license, had to printed it out. The printer was low on a few inks, so the only non-black color is now yellow, and we're out of paper. Take a moment to consider the problem with having to learn from traffic lights with three yellows, yellow stop signs, and yellow cones (used to describe what orange, yellow, and red cones signify. and they are all yellow). A certain Coldplay song comes to mind. Kudos to whomever can guess which one. Meanwhile, I'm going to go try to evolve my eyes to see a wider color spectrum. Have a nice day!
