In common with many other folk, I am currently taking a LOT of daily medication - pills for this, capsules for that. Some are once, twice or three-times a day, some are only once-a-week and on the day you take those there are others that you mustn't take.
It's potentially confusing and, although only two-thirds of the way to my dotage, I make mistakes: forgetting this or that dose just too late to squeeze one in before the next. Now, if I'm challenged by this regime, how much harder must it be for those who are (really) elderly or have sight-impairment? In fact, having lived in close proximity to several veteran pill-takers, I don't even need to ask the question, I know the answer...
I mention this as a prelude to a quick rant against the drug manufacturers in this country who seem incapable of agreeing on colour-coding for pills and capsules.
Two of my drugs have changed colours - one of them twice - in less than a year, which means that just when you've got used to remembering that blood pressure equals a pink-and-white capsule it suddenly becomes a pale-green-and-white capsule and then, only a month or two later, inexplicably changes again into a yellow-and-white capsule!
So, why use any colours if they're not important? I bet that even among those clever pharmaceuticalists there are those who avoid orange-coloured Smarties or green-hued Wine Gums! So, why not just settle on a colour combination and bloody well stick to it, then everyone knows where they are and - more importantly - what they're on!
