Hey. Hope everyone enjoys the quiz. It's not too hard, is it? Or is it too easy. I always read my comments on quizzes, so feel free to add a comment or complaint and I'll fix it, make it, delete it, make it easier or harder. And don't forget too try out some of my other quizzes. You never know, they might be better than this one.
Confident is an odd choice. My first thought was unconfident, which would seem to be the truest antonym for the word. Also, my first thought for colorful was drab. Maybe stick to words that have a clear opposite like the others you chose. Overall, a good idea for a quiz.
