Struck by a rainbow. Wonderful sentence, provocative and fun. Could mean anything. It could describe the transformation that happens whenever you eat a Skittles.
In this particular case, when the gentleman who is the subject of this mockumentary was “Struck by a rainbow.” his skin turned into Skittles. His entire surface is now made up of color coordinated Skittles matching his pre-Skittles features. His lips, of course, are red. He is much like a candy Lego man except the individual Skittles sometimes come loose.
When taken semi-seriously, the device lends itself to funny lines, “That’s all everybody does is pick at me.” and funny scenes like a kiss leading to a nibble.
Viewers infer the qualities of a brand from what the brand does and its advertising is an action of the brand. To reveal those inferences, you can ask “What sort of a brand would make an ad like this?”
Viewers will conclude that the brand that made this mockumentary is wacky and creative, desirable qualities for a brand of candy. Though they might also conclude it is weird maybe even a little creepy. Viewers will not infer delicious or appetizing. Nothing about the ad is appetizing.
The ad works but another interpretation of what it means to be “Struck by a rainbow.” might do more for the brand.
