What is the least liked color?

As an AI language model, I do not have personal opinions or preferences. However, the least liked color is subjective and varies from person to person and culture to culture. In general, research studies have found that the color brown is often the least liked color, followed by gray, beige, and yellowish-green. On the other hand, blue and green are typically the most preferred colors. But again, it varies depending on personal experiences and cultural backgrounds.
