Balloon icons are a type of icon used in graphical user interfaces, often as a visual representation of a button. They are typically colourful and may be in the shape of a balloon, or may be a simple circle, square or other shape with a balloon-like pattern inside. They are commonly used to denote a specific action, such as a warning, or an alert. They are also used to indicate a particular state, such as a completed task, or a successful operation. Balloon icons can be found on websites, software, and mobile applications. They can help to visually explain a certain action or state, making them a useful tool in user interface design.
