Case 1: Fail
Case 2: Fail
Case 3: Fail
Case 4: Pass
Case 5: Fail

When I have decided if something passes or fails after applying the heat map
I usually ask myself "Does what I see still resemble letters?" Except for #4
your examples do not.

I hope this helps.

Subject: [WebAIM] Chrome Color Contrast Analyzer

I was told that the Chrome Color Contrast Analyzer is the best way to tell
if there is sufficient color contrast between text and background color
because it actually works off the resolved images that the user will see.
But I am not always sure whether the heat map generated indicates a pass or
a failure. It's not exactly a binary "legible" or "illegible" that often
Can someone help by taking a look at the samples I've arranged at ? Would you consider these passes or
failures? I am deliberately not sharing the original html pages since that
would influence your ability to comprehend what you see in these heat maps.
If there are other tools as easy to use as this one but which give results
easier to interpret as passes or failures, I'm eager to hear what they are.
