To change the color of text in HTML, you can use the following methods:
1. Using the CSS color property. Set it to the value you want and place it inside a style attribute. Then add this style attribute to an HTML element like a paragraph, heading, button, or span tag.
2. Using an inline style attribute. Add the style attribute to the element and type the color: attribute inside the quotation marks. Type the color you want to change the text to followed by a semi-colon (";").
3. Using internal CSS. Add a style tag to the head section of your HTML file. Inside the style tag, type the CSS code to change the color of the text.
