```I have been attempting to take this concept to the next level - to have the
barchart colors cycle through a set of 3 different vertexcolor schemes
across 12 different values, as one gets when you have BarChart[
{{1,2,3},{4,5,6},{7,8,9},{10,11,12}]

what seems missing is the ability to define a set of rules that are applied
in sequence i.e.  "the first time you see this pattern,  do X,  the second
time, do Y, third time, do Z,  fourth,  do X again and keep cycling.  "   I
know I can extract the cases or locations of the pattern matches,  and yes,
you can then use Riffle and generate a complete ruleset to do the
replacements.  it just seems like alot of complexity for what seems should
be simpler.. any way to use convolution???
