I've seen this brought up before but WotC, seriously, you need to change the colors for the faces when asking if someone had fun during a match. When you're clicking through, most(good) designers use red for bad and either blue,white, or green for good. It makes no sense you chose to color the smiley face red and the unhappy face blue. This is Design 101 and I know I've mistakenly clicked the wrong portrait numerous times.
Also, yes, reading the card explains the card. It's not entirely their fault(we should be more diligent), but good design follows human nature/tendencies, not fights against it. Red typically symbolizes caution or something negative, while blue, white and green symbolize something good.
