Oracle APEX (Advanced) - Highlight row based on condition

I have this query on a classic report

SELECT   w.vendor, w.qty, r.rec
    FROM (SELECT   vendor, SUM(ord) AS qty
              FROM wag where ship_date = :P0_DATE
          GROUP BY vendor) w,
         (SELECT   vendor, SUM(ord) AS rec
              FROM recinc where "sDATE" = :P0_DATE
          GROUP BY vendor) r
   WHERE w.vendor = r.vendor
ORDER BY vendor

That query gives me the results of the attached image

I want to highlight rows where the "Ordered" and "Received" column do not match

12 and 12 would not be highlighted
12 and 10 would be highlighted.

I am looking for someone to walk me through the process, i have been researching for a couple of days now and have not found a solid solution. any help would be greatly appreciated.
