counting strings in mulitple columns in a pivot

I am having an excel problem ...

I have a data set that looks similar to the data below. My issue is there are three category columns. I need to sort count totals for each of the categories using a pivot so I can filter on the state, group or any combination of those.

I would like it to look similar to this:
row labels, a, b
red, 5, 4
yellow, 2, 3
blue, 1

or

row labels, red, black, yellow
Hawaii, 5, 4, 3
Florida, 3, 3, 5
Delaware, 5,1,3

Any advice would be appreciated.

Thanks
