What is an example of a small detail that can make a big difference in marketing?

"One small detail that makes a difference when marketing a product is color. Whether it's through online advertising or the packaging it comes in, it plays a large part in helping customers get the essence of the product before they try it. For example, if a company is marketing grape soda, I would advise them to make the packaging a shade of purple that is commonly associated with grapes. If the grape soda comes in an orange package, this will repel grade soda lovers. First of all, they may not even notice the grape soda in the orange package since grape soda is seldom if never, associated with the color orange. Next, if they notice the grape soda in the orange package, they may suspect it won't taste like grape. They'll likely err on the side of caution and pass on the product. This is an example of how something small is a big deal and can be the difference between product selling or being ignored."
