What is what does blacker the berry the sweeter the juice mean?

The phrase "the blacker the berry, the sweeter the juice" is a saying that suggests that darker-skinned people or things are often more desirable, more attractive or more flavorful compared to lighter or paler ones. It is commonly used in reference to black people, particularly women, and their physical appearance. However, it can also be used to express the idea that more challenging or difficult experiences can lead to greater wisdom, strength, and resilience.
