What to build next? Inspirational and original reference material has been a cornerstone of the Scale Aircraft Modelling magazine since its inception, and ‘Colour Conundrum’ is designed specifically to offer the modeller something different. With original research based on surviving records in the National Archive at Kew the aim of these articles is to throw fresh light upon some old questions, to challenge some long held views on aircraft camouflage and markings, and to pose new questions that had arisen as a result of the research to which the answers were not yet known. Quoting extensively from primary sources, the articles also provide valuable insight into the organisation and administration of the air force, and the many thousands of documents and memos that passed from office to office behind the scenes, providing background and understanding that add depth and focus to a model, as well as an opportunity to understand why a specific colour scheme may have been either selected or rejected. Author Paul Lucas’ work is regarded as both valuable and unique in current aviation publishing, and this selection is collected together in book form for the first time.
