My report looks like this:

Column1   Col2      Col3   Col4   Col5
Type1     type A    sum1   sum2   sum3
              type B    sum1   sum2   sum3
Type2      type A    sum1   sum2   sum3
              type B    sum1   sum2   sum3
              type c    sum1   sum2   sum3
Type3     type A    sum1   sum2   sum3
              type B    sum1   sum2   sum3
Type4     type A    sum1   sum2   sum3
              type B    sum1   sum2   sum3
              type C    sum1   sum2   sum3
              type D    sum1   sum2   sum3

I want to highlight the summary fields based on Column 1 value.
If col1="Type1" then col2,3, 4&5 should be highlighted with red color
If col1="Type2" then col2,3,4 &5 should be highlighted with blue color and so on
I want a color differentiation between the segments Type1, 2,3 ,4& 5.

Thanks in advance
