Urban Geometry Series: London: High Street Kensington
Gum marks on the street seemed irregular dot pattern of warm grey concrete background
with black dots (old gums) and light grey dots (recent gums).
Researching the neighbourhood, I saw colourful flat doors; green, blue, yellow, red, brown and so on...
Then I imagined the trodden gums on dirty grey concrete becomes colourful as my London was colourful.
