Hi again, Sherman. I removed magenta from the pics, and the background tones became more natural on my screen, but the pink (more pale mauve, I'd say) remains on the outer beach. I think this might result from a sorting of heavy mineral sands (Zircon). But perhaps others are right about an organic origin. It is unlikely that beach sands would be anoxic enough and laden with sulphides to harbour "purple Cyanobacteria" (I don't know current taxonomic assigment), which produce this sort of colour on saltmarsh muds. Cheers, Ian McLaren
