Coloring Entire Rows Based On Certain Logic

Here is my attachment with data in first sheet and expected output in second sheet. Have given comments in second sheet for better understanding.

Data is of a debt collection, in sheet column F "form #" denotes loan form numbers and column L "paid" denotes the amount received or not received.

In this Form # are unique and form number will repeat with different paid amount.

Entire row to be colored based on the sum value of paid column amount of respective form number.

1. non repeated single form number with negative value of paid - Orange color

2. repeated form numbers with sum of values in paid column as positive value - only entire row of form number with negative value in blue color

3. repeated form numbers with sum of values in paid column as negative value - first form number row to be colored with yellow and rest of repeated form numbers with purple color and its sum value (negative value should be made available in yellow line of the Form # group to the right of right most column data)

4. form numbers and paid column of value "0" - pink color

I tried recording and edited macro only for the logic of paid value "0" and confused with other logics and declaring variables...
