Daylight differentially reflected as colours by
metals and chemically dyed oxide particles.
These "pigments" are suspended in
a mixture of linseed oil with

( both derived from coniferous trees )
The relationship between viscosity and gravity
becomes evident as
the "oil colour" is absorbed into the
translucent surface of white pine board.
The background is
"stained" western red cedar.
