I am generating a BIRT report as shown by image embedded, I am grouping by custmeer such as ACM , AFL etc …
As you can see I use background alternative color as blue and white, to achieve this I simply use the highlight tab of detail row as(row["__rownum"] % 2 Equal to 0).
now , if I move into more complexity such as different color combination for different groups e.g for group(customer in this case) yellow-white, for group2 red-white etc….
I am using this.getStyle().backgroundColor ='color', but the problem lies into selecting the individual groups, may be some sort of in condition would do the trick, but I am lost

The simplest way to set a row's background colour in BIRT is by adding conditions to the list in the Highlight tab within the Property Editor for the row. It looks as though you have already done this to set alternative lines to blue - by adding extra conditions with additional colours, you can set the background accordingly. This method is most useful where only a small number of colours are required, since you have to set up a different condition for each colour.
Where a larger selection of colours is likely to be required, it would make more sense to do conditional formatting within an event script - you can find an example here.
EDIT: Adding a running group count in BIRT:
1/row[
first aggregation name]
and the Aggregate On to be Table.The second aggregation item will be a running count of the groups in the report.
