According to Raven in
Warship Perspectives, Camouflage Volume One: Royal Navy 1939-1941, on page 33, he states that "
Warspite wore this pattern (referencing the drawing on the page) from early 1941 (exact date unknown) to the end of her career with only small changes".
Warspite, of course, wore a second pattern starting in 1943. The author does correct that error in his next volume.
His volumes don't have any mention of
Barham that I recall, but he does mention in volume one that ships operating in the Mediterranean started painting out of straight 507c light grey and into disruptive camouflage by August 1940. He also states that "This type of camouflage, known as the 'Alexandria type' was carried on almost every ship based at Alexandria beginning in August 1940 and through 1941".
Finally he shows a rendering of
Malaya wearing a scheme similar to
Barham's when she served in the Med. She wore that pattern from August 1940, even after she moved out of the Med, probably until March 1941.
It's not a stretch to think both
Warspite and
Barham were both sporting camouflage patterns that night.
Here's the Warspite's pattern:
