Somebody, not clever, add color to developer js-console, ignore rules for good contrast text vs. baground.
If you not know, how compute, you can use my non-oficial formula, page https://mlich.zam.slu.cz/col5.htm
Put there background color, then text colored white or black (lighter or darkness) for good contrast.
Why i write this? I have still problem use console, look on error code line. number is 180 185 186 or 189? You can see this by eye, because ther is low contrast. shadow-dark-red background, shadow-light-cyan text. Visibility zero.
