Black, white and green.

The large black rock stands noticeably among the smaller coloured rocks on this seashore south east of Dunbar beside the John Muir Way. I'm not sure if it's basalt or maybe obsidean but appears to be an erratic igneous boulder, probably from the local volcanic activity millions of years ago. Perhaps someone can tell me. White gulls were eagerly scanning the foreshore as the white waves crashed on to the shore on this beach of white sands. The white lighthouse in the background is at Barns Ness and after 104 years its light was switched off in 2005. Green seaweed.
Just beyond the lighthouse is a very interesting geological trail with many fossils found among the sedimentary rocks on the shore. (For those interested in geology; most noticeable are the innumerable regularly spaced metre wide hollows in the limestone in this RIGS and SSSI)
