By way of example, if I apply your solution to a StackedBarChart it works w=
ell :

StackedBarChart[{1,2,3}, {3,3,3}]/.Rectangle[{x1_,
y1_},{x2_,y2_}]=A6Polygon[{{x1,y1},{x2,y1},{x2,y2},{x1,y2}},
VertexColors=AE{{1,0,0,0},{1,0,0,0},{1,0,0,y2},{1,0,0,
y2}}]

However, what if my StackedBarChart has two colours on each bar, eg:
StackedBarChart[{1,2,3}, {3,3,3}, BarStyle=AE{Yellow, Black}]

So my question is, how can I get the changing colour intensity up the bar (=
which has been achieved on the BarChart) on a StackedBarChart, where each b=
ar has two colours ?

Thanks - I appreciate your help,
