I recently posted this question on apple.stackexchange which contains a hex dump, like this:
00000210: 616e 7369 6f6e 0a20 2020 2020 2020 5f08 ansion. _.
Different to here (on Meta Stackexchange), the hexdump in apple.stackexchange was syntax coloured - some hex values displayed in red and some in green.
Is there a deeper meaning in these colours? I wonder according to which rule the colours are chosen here.
