The problem is probably with your monitor, such as using a laptop,
or even your color settings. Though color blindness is another possibility
and a good reason that data should not be relying on color to convey
information (and printing in B&W is the norm).

For instance on my laptop of the 16 basic computer colors, about
seven of them look black unless you look at an angle or adjust the
colors to simulate looking at an angle.

You can change a color in the palette to another color, and it
will apply to the entire workbook. There are 56 colors that you
can have

It's impossible for many people to distinguish between black and dark blue -
the colors used for filtering indicators in Excel. Is there a way to change
the dark blue to something more visisble, such as red??????????
