Grey on white text

[FileproPlusGuy]

Unless its required for some arcane purpose, the first black background example of code (and subsequent) should use a slightly darker font so it shows up on the white background (the white on black background is fine), otherwise it's hard to read. I'm relearning BASH at 68yrs, so please make it easier to read.
Same goes for those color choices on the 'terminal' side, readability should be first on your mind, salience second.
