Hi Francesca,
This is not for LIST UIBB but for ALV see if this helps you..
I have not tried below code but might work for you.. You need to use TEXT_VIEW to get this done.
Get all columns and loop through.
alessandroiannacci.it/default.asp?det=10
lt_columns = lo_column_settings->get_columns( ).
LOOP AT lt_columns ASSIGNING <fs_columns>.
lo_column = lo_column_settings->get_column( <fs_columns>-id ).
CASE <fs_columns>-id.
WHEN 'EXPIRED_PRO'. "Red text
DATA: lr_text_view TYPE REF TO cl_salv_wd_uie_text_view.
DATA: lr_ui TYPE REF TO cl_salv_wd_uie.
lr_ui = lo_column->get_cell_editor( ).
lr_text_view ?= lr_ui.
lr_text_view->set_semantic_color( value = cl_wd_text_view=>e_semantic_color-negative ).
ENDCASE.
ENDLOOP.
