It definitely looks like a dark color... however... some of the early film emulsions would not register colors in the yellow range. This could cause the negative to show anything 'yellow' (including yellow metal like brass or copper) as unexposed. As a result, the silver would wash off the film substrate during fixing. Then when printed, the final print would show the color as dark or black.
I have to scan them and will post tomorrow. But we have some original pictures of the RR Springfield works that drove us nuts... because it showed all the 'brightwork' in the engine bay as black. Yet we know that these parts came bright. In the prints, however, they all look to have been blackened. This includes brass carb, copper lines, etc. It took several years before the mystery was solved...
Finally, I found the answer in a c. 1950's Leica manual that I got for Christmas last year. The Leica handbook talked about early emulsions and how they weren't fully panchromatic. Film prior to the late 1920's could be insensitive to light in the wavelengths reflected by yellow. As a result, yellow will come out looking black!
That doesn't mean that the bike in this picture is not a dark color (or a rich color like a deep red.) It certainly looks like it is. But there 'is' a possibility that all these bikes were yellow and that this picture is distorted by the early emulsions.
