Depends on the age of the Hurri. Some where painted in the field and the later marks where painted at the factory. Found this comment on Brit Modeler. However, given the desert environment and mother nature's work on airframes . . . freehand works. Lookin good.
"This is common on desert Hurricanes. It may be that the design office simply changed the label on the drawing from DG to MS, but the painters took the darker shades on the drawing to be the darker paint. The darker colour in the photo is Dark Earth. Dark Earth did fade quite quickly in the desert bus not to be lighter than MS.
Given that this is a Mk.I, there appears to have been considerable variation in which colours went where - there are photos of early aircraft where examples with different colour variations can be seen. This is probably because aircraft delivered in DG/DE were overpainted in the Alexandria MU simply by overpainting the DG with MS, as (apparently!) originally intended. Aircraft were being delivered in the Temperate land Scheme well into mid-1941, the Greek campaign for example. It is worth remembering that the Middle East covered a much wider range of climate conditions than the Western Desert. However this seems to have stopped by the time the Mk.IIs appear and the factory-applied scheme is more common if not universal "
