Sometimes we want to color the same id (or something else) in the same color.
Although not strictly a reporting procedure, one of the most important procedures in the would-be traffic lighter’s toolkit is PROC FORMAT. User defined formats allow the SAS® programmer to define foreground (font) and background color.

PROC TABULATE

 In PROC TABULATE, background and foreground colors via a user-defined format can be applied in the various style statements (for example, the PROC statement, the VAR statement(s), CLASS statement(s), the CLASSLEV statements(s), the TABLES statement(s), and the BOX statement.) They can also be applied in a user-defined style template. Colors can be assigned directly in the style statement, or with a user-defined format.
STYLE ON THE PROC STATEMENT:
In general, you would not use style on the PROC TABULATE statement for the purposes of traffic lighting, as it applies an overall style to the table rather than highlights particular values. Nonetheless, it’s fun to play with while formatting your reports.
Syntax:
Proc tabulate data=yourdataset style={background=lightblue}; This would create a light blue background for your table regardless of what overall style you use.

proc sort nodupkey data=all_r out=list_value;
by id;
run ;

proc sql;
create table formats as 
select  a.id as start,
        a.id as end ,
        color as label,
        'color' as fmtname
from 
(select a.* ,monotonic() as misp
from list_value a ) a,
 color1 b
where a.misp=(b.misp-5);
quit;

 I calculate misp-5 in order to remove the black color.

 exposure=' '*(  mean= 'exposure' *f=comma10. )*[style=[  font_weight=bold]];
run;

The result:
