Problem
Create a servlet code by making a small page that displays some simple information of your choosing. Make another page that lets users choose the foreground and background color that they want the first page to use. For example, if users never visit the the color choice page, the main informational page should use default colors of your choosing. But if a user visits the color choice page and chooses a yellow background and red foreground, all subsequent visits to the main page by that user should result in red on yellow. There is no need to vet the colors; you can accept whatever color values the user gives you.
