What is the blacker the berry the sweeter the juice origin?

The phrase "The Blacker the Berry, the Sweeter the Juice" is an old African American proverb that suggests that darker-skinned people have a sweeter and more desirable personality than those with lighter skin. The origins of the phrase are unclear, but it has been used for many years to describe the beauty and desirability of dark-skinned women. In recent decades, the phrase has been used in popular culture as a way to celebrate black pride and to promote positive self-image among people of color. However, the phrase has also been criticized by some for perpetuating colorism and for promoting stereotypes about race and skin color.
