Coloring alternate cells of one column in different color

Dear Experts,

Would love some help in this project
Basically the attached excel sheet lists out different fields with color sequencing except column I

Of interest to me is the column I which may have any n entries , so the macro to first take into account for rows in the sheet ...basically different sheets have different number of entries and i would like to reuse the developed macro ,

Here the different entries reflects basically different topics
What i am seeking is a macro which color codes every alternate entry in this column some sequence
Like Cell I2 blue , I3 green, I4 blue , I5 Green , I6 blue , I7 green ...
Remaining sheet color sequence shall remain as it is ,

The attached workbook has one tab titled input and other titled Output
In the input tab , the color code is not defined for the column I entries ...in output tab , i have done the color coding i.e defined what i am expecting when the macro runs ----- for the first few entries in column I ,

Can anyone please help ,

Humble regards ,
