These are Astronomy slacks. The color is brown. I bought them about 10 months ago, but I'm selling them because I don't wear them anymore. I've included examples of how to wear them in the 3rd and 4th photos. I've paired them with a shirt as an inner layer, but I think wearing a tank top underneath would also be good. I hope this helps you when considering a purchase. Also, they are stored in an environment with dogs and cats, so please consider purchasing only if you don't mind. Thank you for looking.
