Crest "Yellow isn't always cute." spec ad

This spec ad for Crest Whitening nails humor and clarity in one shot. A smile full of yellow, Minion-like teeth instantly grabs your eye and delivers the message: yellow isn’t always cute.
Marketing Analysis
The ad uses contrast and surprise. You expect something “cute,” but end up with something slightly gross. That tension makes you laugh and remember the product’s benefit.
Why It Works
- Simple visual, instant message
- Humor softens the “gross” factor
- Bright colors grab attention
- Unexpected twist sticks in memory
Examples
- Snickers’ “You’re Not You When You’re Hungry” plays on contrast too.
- Old Spice used absurd humor to make body wash cool again.
- Colgate’s missing-tooth ads highlight plaque by showing what’s not there.
