Apparently, Beverley's favourite colour is green, hence the basic colouring used on this site.

The background colour is #99CD99 or RGB(153,205,153).
This has no offcial name; I call it Dark Patina.

Highlighted panels are #C0E9C0 or RGB(192,233,192). This also has no official name; I call it Patina.

Symbols (mainly Webdings font) are #CAF0CA or RGB(202,240,202).
I call this Bright Patina.

Patina is a film of copper carbonate that forms on weathered surfaces of copper and bronze, such as the roofs of some buildings.
