Sorry, but no. In the current ColRegs (which date from 1972, plus later amendments) all day shapes are black, presumably so they appear as silhouettes. However, the previous set of rules had coloured day shapes. One of my first jobs on joining a seismic ship as a student about '69, or '70. was to repaint the RAM shapes: the colours matched the lights, red, white, red.Orange shapes might be more visible but I suppose the reason it is black is because in the days when the ColRegs were first compiled, orange paint would not have been readily available whereas black paint or tar would have had its place in any boatswain's locker.
