The ones I failed on were all on the search box because this is such an incredibly bad design unless you are using an incredibly high contrast screen in the dark. I'm sat here using a pretty decent gaming laptop with a good screen and I can barely see the difference between the white search box and the grey background. Whenever I'm doing any UI design work (or assessing something developed outside) I have a cheap and nasty AOC monitor with crappy contrast hooked up and at an angle as a second monitor, so I can see how it will look on the type of monitors a lot of people use. If it looks good on that and on my nicely colour calibrated screen great. If I can barely see it, its not getting shipped.
