What CSS property controls the text color?

The CSS property that controls the text color is "color." This property is essential for formatting text within HTML elements, allowing web developers to specify the desired color in various formats such as named colors, hex codes, or RGB values. When you apply the color property to an element, it directly influences the color of the text within that element, thereby enhancing the visual aesthetics and readability of the content on a web page.

The other options listed do not correspond to any valid CSS properties for controlling text color. "font-color" and "text-color" are not recognized by CSS and will not have any effect when applied. "text-fill" is also not a standard CSS property; it might be confused with properties used in SVG or other contexts for graphics but does not serve the purpose of coloring text in HTML documents. Understanding the correct property is crucial for effective web design and development.
