Perhaps background color could have pattern
I worry it might make legibility fuzzy.
If 1 or 2 characters could be selected to have non-linear visual properties e.g. went above or below the line then it helps the brain map a string of otherwise flat text.
Actually, i you're looking at a list of these on a webpage, it will confuse the brain because it's been taught that certain legible lines belong in just that line....
Better. I think when the same or similar colors are neighbored it's easier to look at. McDonalds picked red and yellow to get people to leave faster. The contrast is uncomfortable.
This inspired the most amazing thought: Math might show some addresses are more "lucky" than others. And there is a better way to display the multi-dimensional forces involved.
Not exactly luck in this case lol. But my life was definitely; well; extreme to the point that just proves I was set apart by both sides of the war to put it shortly.
Excellent idea to explore ! Lower-case has descenders, Upper Case bores straight perhaps limiting it to numbers or hexadecimal set (0-f) I will test "superscripting" hexadecimals
