Thought it might be nice to have a break from monochrome
Not that I dislike white/grey/black of course (and it is in keeping with the rest of the site), but a random dose of colour in a subtle way makes things more amusing. It also helps to see if you are stuck behind a transparent web proxy that isn’t updating properly (*cough*NTL*cough*).
Not sure how bad they’ll look on 8-bit displays, as (thankfully) I don’t have to suffer that indignity much these days – it’ll be a quick tweak to the array if they do seem too bad, if I get around to testing it…
