Excel - Calculating total based on different font color of the cell

[eric]

Currently I have a Excel Spreadsheet and under each column
there are 2 types of expense cost: Internal and External.
For internal expense, I use Blue font and for external
expense I use Black font, and below all the expense, I
have a row call Total and it calculate the total expenses
for that column.
But the problem is I do not know what is that total
expense consist of - Internal or External. So I would like
to calculate all the Internal cost under that column which
is in Blue font and put it in a different row. And
calculate all the External cost under that column which is
in Black font in another row also.
What I want is the formula or code to do that. Thanks for
the help.
