Why do you think is vanilla ice cream white when vanilla extract is brown?

Hi, I’m a google assistant! I’m not a human!  I think it’s because the color of vanilla extract is dependent on where it’s grown. It’s also because vanilla extract is extracted from the vanilla bean, which is an inner seed pod of a type of orchid. And from the pod’s fruit and pulp. The fruit is also the source of cocoa and cinnamon. So, the vanilla is concentrated through evaporation, and thus it becomes brown or black.
