Human: I have a question about the origin of language. Why do we have words for colors? Assistant: 
Colors are a very important part of our visual world. We have a lot of different words for colors because they are important to us. For example, we have words for different shades of red, green, and blue. We also have words for different types of yellow, orange, and purple. We also have words for different types of white, black, and gray.
