Dark Theme Simulator is a Chrome extension that offers a solution for users who prefer dark themes on websites that don't provide them. When faced with a webpage that can only be viewed in a white background, this extension comes to the rescue. By clicking on the extension icon, the colors on the page are inverted and softened, creating a more comfortable browsing experience. It also attempts to restore images to their original appearance, although there may be instances where images appear as negatives.

This handy tool is particularly useful for those who enjoy dark themes but encounter websites without this option, enhancing user experience by providing a dark theme simulation for a more visually pleasing browsing session.
