Sites contrast borders on violating accessibility guidelines

See title thats it basically, see example below.

• The purple in $ ssh hackclub.app and more places

From my limited search, the purple above appears to be the only colour not contrasty enough (is that a word?). However, it may be worth increasing the contrast of other colours used, like the gray buttons below (oh and another appearance of that purple).

Not rather sure if this is something which needs to be changed, or if I'm just overly worried, but thought I'd just make an issue. Let me know if I'm just yapping for no reason lol.

Good catch! I'll PR a fix to those colors later today
