Virginia Howlett, a pioneering interface designer at Microsoft since 1985, was part of the team that created the themes for Windows 3.1, including the vibrant "Hot Dog Stand" color scheme. This theme featured bright yellow and red and was one of several color palettes designed to allow user customization. Howlett noted that the user interface primarily used black lines on a white background with shades of gray for 3-D buttons. She expressed surprise at the continued interest in Windows 3.1 as it approaches late 2025. The Hot Dog Stand theme was not intended as a joke but rather as a memorable design choice in the history of Windows.
