macro: changing color of coloumn header based on rows color

Hi Experts,

I wrote a macro to color the cell values in the rows based on their average value. For eg if the cell value is less than 0.2 Avg, they should be red color,if value is between 0.2 and 0.5 it should be yellow. This part is working fine

Now based on the color of the rows cells , need to write a macro for the header one. Logic is Coloum header should be in red colour, if in one or more number of rows cells are red. same with yellow ones. Could you please help me out in solving this with logic.

Thanks & Regards,
Raj
