[James A Pratt III]

Here what I got from "Fighting Colours" by Michael J.F. Bowyer which came out in the early 1970s and may be somewhat dated:
"All of the fighters still had brown and green upper surface camoflage. Type A roundels on the fuselage sides in the Middle East area had a yellow ring added in June 1940, and Type B roundels were placed above the wings when camoflage was applied. Type A roundels beneath the wing tips were the usual. During the campaign in Greece some Hurricanes were seen with half black under surfaces and some certainly had the remainder of their under surfaces light blue, although 'all-Sky" (duck egg green shade) was usual."
