"Color can convey subtle messages to shoppers, and this corrugated PDQ from Alka-Seltzer sends a cool, soothing signal with its prominent use of blue -- both on the display and packages.
Add a few effervescent bubbles to complete the soothing effect and relief is just a few sips away. I also like the bilingual copy treatment. It doesn't detract from the overall appearance and serves the growing Latino segment of the population."
