How to control colors when writing spool using REUSE_ALV_BLOCK_LIST_APPEND

Hi all,

Can anyone help me how to control colors when writing spool using "REUSE_ALV_BLOCK_LIST_*" Function modules??

Currently I am getting colors for List/Grid header and when I do any Totals/Subtotals.

My requirement is that the spool should not contain any colors. So I want to supress all the colors.

Please suggest me on this.

Thanks,

Prabhu
