Since the 'B' Phase colour here has been changed from Yellow to White (in accordance with International convention, so I'm told),

I'm not sure what international convention that would be. [Linked Image]

In the U.K. red/white/blue was the standard up until 1964, as which point B-phase changed to yellow, which is what it is today (until the old colors are fully displaced in a few months by "that" color code).

So far as I'm aware, RYB (or RWB) has only ever really been a standard in British/Commonwealth countries, or those so influenced.
