Which CSS property is used to change the text color of HTML elements?

The property used to change the text color of HTML elements in CSS is "color." This property allows developers to specify the color of the text content for an element, using various color formats such as named colors, hex codes, RGB, or RGBA values. When applied, it directly affects how text is displayed on the page, allowing for customization of the visual presentation of content.

Other choices do not exist as valid CSS properties for changing text color. For example, "text-color," "foreground-color," and "font-color" are not recognized properties in CSS, and using them would not produce any effect, as they do not impact the styling of text elements. Understanding the correct terminology and properties in CSS is essential for effective web design and development.
