Hold on though, didn't those green-on-green buttons actually work fine for the other 90% of your users who aren't colorblind? You added icons and boosted contrast for a small minority, but now the whole interface is visually cluttered and harder to scan for everyone else. If the original design was clean and consistent for the vast majority, maybe you just overcorrected instead of leaving well enough alone.

Wait, you spent a full hour on it? Man, that's brutal. I would have caved and checked after like ten minutes of nothing working. It's always the simple stuff that gets you, like a loose neutral on a outlet you just replaced. Makes you feel kinda silly, doesn't it?

But what if the work is the only thing that matters? I mean, @briannguyen, on a delivery job, a fast driver who gets every package right but is grumpy is still way better than a nice, slow one who messes up addresses. Sometimes you just need the job done right, even if the person is hard to be around.
