I just spent a couple of days working on colors for a project, and I had all those little Pantone chips spread across my desk. I wasn't picking yellows, but Dole was. Check this...
"Speaking of fruit, you may think a banana is just a banana, but it's not. Dole and other banana growers have turned the creation of a banana into a science, in part to manipulate perceptions of freshness. In fact, they've issued a banana guide to greengrocers, illustrating the various color stages a banana can attain during its life cycle. Each color represents the sales potential for the banana in question. For example, sales records show that bananas with Pantone color 13-0858 (otherwise known as Vibrant Yellow) are less likely to sell than bananas with Pantone color 12-0752 (also called Buttercup), which is one grade warmer, visually, and seems to imply a riper, fresher fruit. Companies like Dole have analyzed the sales effects of all varieties of color and, as a result, plant their crops under conditions most ideal to creating the right 'color.' And as for apples? Believe it or not, my research found that while it may look fresh, the average apple you see in the supermarket is actually 14 months old."
