What does the fill colour button do in a spreadsheet?

The fill colour button in a spreadsheet is designed to apply a background color to the cells that you have selected. This function allows users to visually differentiate between different sections of data, highlight important information, or simply enhance the appearance of the spreadsheet. By changing the background color, it helps make data more readable and organized, which is especially useful when working with large sets of information. This feature is distinct from changing the color of the text, adjusting borders, or formatting text styles, which serve different purposes in spreadsheet design and presentation.
