<human>:  What are the differences between types of soy sauce?
<bot>: The primary difference between types of soy sauce is the level of saltiness. Light soy sauce is lighter in color, thinner in texture, and has a saltier flavor compared to dark soy sauce. Dark soy sauce is thicker, richer, and has more of a caramel flavor. Additionally, some versions of dark soy sauce include other ingredients such as spices, sugar, and coloring.
