On first glance, achieving the formatting you show in the example won't be easy.
You may want to try the alternative of shading rows in alternating colors
whenever the value in a particular column changes.

You can try out the "Shade Data Rows" add-in from my website to see if
that approach is close to what you need.

Column A has been sorted with a blank line after each unique entry. I
would like to format the first occurence in Column A as well as Column
B with a background color. Column B will continue with that color
until Column A has a different value, then a new color will be applied
for the next grouping.

This report is somewhat dynamic where there may be 5 to 20 uniques in
Column A so I need atleast the ability to use up to twenty colors,
which I can predefine in a case.

The example of what I'm trying to achieve is:

There is no code in the example above, it's just for example.
Does anyone have any ideas on how to do this?
