Count number of trips by occurences

Hello,

I have a table with 31 days; each day consists of 15 groups; each group consists of several trips; each trip has only one of the 3 colors (value =1). I need macros to:

1) For each color, count the total number of trips that have the same sum of color = 0, or 1, or 2....
2) For each trip, mark similar trip with a code (so I can do grouping later). For example, in "Color 1" column, all trips that have the sum of color = 1 are marked as "C1_1", sum of color = 2 are marked "C1_2", etc.

Please see the attached Excel file as a sample of original data and desired outcomes (shaded).

I appreciate your help.
