Has this issue been resolved, or a fix created? I totally agree that the blue
color is next to imposible to see, especially if several columns are involved
in the filter.

I suggest that Miscrosoft changes the color of the Filter Drop Down List
Arrows to Bright Red, when the column is filtered. Trying to distiguish the
non-filtered columns (black arrows) from the filtered columns (currently dark
blue) is almost impossible.

Make this drop down arrow Bright Red would make it easier and obvious that
the spreadsheet you are viewing is limited by a filtering critieria.
