yea you gotta really squint, id recommend putting a more bright color on it
I set the 1 to be white so it looks the most neutral and made 4 cyan and 5 yellow. I switched to the skinnier font and dropped the transparency to level 4 of 5. That stopped all the hard to read number problems.
But agreed, that dark blue 4 is no good. The darker colors in general don’t work that well.
