The word "color" will be followed by a small box that shows the element's text color. You can also filter to all color style definitions by entering "color" in the Filter box at the top. Look for the word " color" in the list of computed properties (they are listed alphabetically). If you have the window docked to the bottom or in a separate screen, it will show up when you click the Computed tab, next to the Styles tab. If the DevTools window is docked to the side of the screen, the computed styles will appear in the right side of the Styles pane. There is also a section that shows the "computed" styles, or final styles applied to the element after all the rules are combined by the browser. The Styles pane shows all the styles applied to the inspected element. If there are two color rules that conflict-for example, an element is defined with gray text in one CSS rule and blue text in another-there is an algorithm that dictates which style will be applied. Combining and overriding of rules in this way is the "Cascading" in "Cascading Style Sheets" (CSS). We are looking for color style definitions, but it can sometimes be hard to figure out which CSS rule determines the final color because the styles that make up an element usually come from different places, even different files.
