	This is a new term for me, "Umbata"...  I ordered something from
Barry called 'Touch of Mahogany', it is out of Copatonic. T.O.M. shows this
same pattern and color (coffee brown with a bold burgundy center on the
falls) as Copatonic, however there is also a spot or flush in the center of
the Falls which is pale violet. There is no 'blending' of the burgundy and
violet either. My guess is that a gene has suppressed all pigments in the
center fall spot area except for the pale violet (anthocyanin?) - meaning
the burgundy area is a combination of pale violet and some carotenoids ?
