1. Cocoa Percentage and Variety Effect Chocolate Bar Colour
Even the same chocolate company can have many types of chocolate with different cocoa types, cocoa percentages, and milk content, resulting in vastly different-looking bars. It's easy to see why chocolate colour varies so much.
2. Chocolate Appearance Goes Further Than Colour
Of course, every ingredient in chocolate will affect the final chocolate bar colour, and lower-quality chocolate bars tend to use other ingredients as fillers to extend the life of their cocoa supply. In this instance, colour and taste go hand in hand, and savvy consumers may be wary of chocolate that appears lighter than expected for this very reason.
3. Packaging Is as Important as Quality
When you send your chocolate out to grocery stores and other second-hand suppliers, your products are likely going to be surrounded by other brands' chocolate bars. Before they can take a look at the delicious treat inside, they'll examine the package for important information like cocoa content. Even more than that, though, they may be taking in the design on the packaging and choosing the most colorful or exciting option in the lineup.
So, while chocolate quality and colour are vital to your long-term success, make sure you spend just as much time on the bar's exterior as what's inside.
