Changing Cell Text Color WITHOUT Using Conditional Formatting Based On Finding Keywords

I have a spreadsheet that uses VB macros to calculate sums of cells based on the font color of the numbers inside. It used to be fairly easy going through each cell and "classifying" them by color, so that my macros can go ahead and sum the numbers in each respective color's cell... but now I have a huge amount of numbers and would like to automate the process somewhat. Here's an example using the A and B columns:

flight $400
hotel $150
hotel $130
meal $20
meal $15
flight $350

I tried using conditional formatting to automatically change the color of the adjacent cells based on the presence of a keyword such as "flight" or "hotel", but this change is only cosmetic, and doesn't actually change the font color (it is still the default black, hence why my color-summing macros won't work!).

I'm including a sample macro for what I use to color-sum my cells, but what I am looking to automate the color-coding process based on looking for keywords as explained above in my example. Here is one of the working color-summing macros (for red, in this case) if you'd like to use it as a reference:

Function SumRed(SelectedCells As Range)
' Adds the values of the cells where the font colour is red(3).
Dim Cell As Object
Dim x As Double
