Right, now you’re all experts on what the shapes mean, what about the colours..... obviously this is hard to tell from black and whites, but there are some rules to follow...

Generally the squadron markings come in 3 colours, Red, Yellow or Blue, which is decided by the seniority of the regiment in the brigade, or they come in White if the regiment is not part of a brigade.

*Regimental seniority will come up again in another thread!

Red is the colour for the senior Regiment in the brigade.
So in our example these Churchills have the A Squadron triangle is Red.

Yellow is the colour for the second most senior Regiment in the brigade, so these Churchills have B Squadron markings in Yellow.

Blue is the colour for the most junior Regiment in the brigade, as illustrated by Bovington’s rather splendid A13 with its Blue A Squadron triangle.

So to recap,
Red = Senior Regiment.
Yellow = 2nd most Senior Regiment.
Blue = Junior Regiment.

But what about White.....?

White Squadron markings as seen on Bovington’s Cromwell mean it’s a regiment that hasn’t been brigaded, i.e Not part of the Armoured Brigade.

In this case the markings are for the Armoured Reconnaissance Regiment from the Polish Armd Div.

So that’s it right?

Well, no there are exceptions and other colours were used in certain circumstances (I’m looking at you 3CLY in Sicily), but as a general rule this was how the Squadron marking colours were allocated.
