The primary colours of pigment are magenta, yellow, and cyan (commonly simplified as red, yellow, and blue).
Indeed - there are two sets of primary colours - additive and subtractive:

I think that's misleading. As has been implied by davelx, it's not a matter of 'simplified' - magenta, yellow and cyan are the usual subtractive primary colours, whilst red, green and blue are the usual additive ones.

It's not really helped by this Wikipedia article. I couldn't make head or tail of the diagrams.

Interesting, because that had never occurred to me before. I tend to only use the 24 hour clock privately to avoid the am/pm confusion, but I bet a lot of official sources using am/pm get that wrong
I missed this until Harry highlighted it.
I really think you're trying to be 'too clever'. Whatever one might think about the literal derivation of "AM"/"PM", they are always taken to mean before/after 12:00 'clock time' (be that when the sun is at its highest, or otherwise!)!

I did say that, but be it a quiz or the wiring regulations people will take what it literally says rather than what they know is intended.
I think the example give may be different - I suspect that, even 'literally, in English (rather than Latin), "AM" probably means 'before 12:00 clock time' or 'before noon' (or words to that effect) - albeit dictionaries seem to be a bit vague/confused/ambiguous about this!
Kind Regards, John
In my opinion AM starts at midnight and ends at noon, PM starts at noon and ends at midnight.
I don't think many would disagree with that - but that doesn't really help, since 'noon' and 'midnight' then have to be defined (during a period of 'daylight saving', like UK summer).

I blame the railways, before railways noon mean noon.
If you want to get really pedantic about the definition of 'AM' and 'PM', within any one time zone there is, strictly speaking, only one precise longitude for which the sun is at it highest in the sky at 12:00 (or 13:00 when there is daylight saving) - move a millimetre, or even a micron, East or West of that longitude and the strict (per Latin) definition goes wrong.
Kind Regards, John
In UK in summer noon is 11 o'clock on GMT ( or Zulu ) and 12 o'clock on BST
Hence the use of the 24 hour clock system
