Mellow yellow

We humans have eyes that can detect just a portion of the wavelengths of radiation that illuminate our world. Thanks to the gizmos that are built into our cameras we can now get some idea of what the world would look like if we could see only one colour, the rest being detected as black and white. Today the colour yellow. 


The photograph is of the remains a WW2 building associated with the LORAN station atop the cliffs at Port Erroll. LORAN, short for long range navigation, was a hyperbolic radio navigation system for ships and aircraft.
The yellow flowers are mouse eared hawk weed; the orange splashes on the walls are lichens; the grasses are very dry and have taken on a yellow hue.


Mellow Yellow is the title of a song written and recorded by Scottish singer-songwriter Donovan and released in 1966. It is also a slang term for the psychedelic drug LSD.
