Core is a cool black and blue browser theme for Google Chrome with great colour palette and graphics. The background image works with even high-resolution 4K displays. This means there should not be any resizing problems usually found with other browser themes. The theme is available in other different colour combinations as well such as blue and green, and purple and pink. This theme is heavily inspired from the game Core but it may also remind some people of the Delos OS. For some, it may give a science lab effect.
