For websites with a gray theme, using accordions with the same color theme will result in more coordination between the components of the website. This accordion normally has a gray background with a bright gray border. When we click on the title of this accordion, the background turns white and the border becomes a little thicker and purple. The color of the accordion text, however, remains black.
