If you’re using the Protractor automation tool for your web testing, you may occasionally need to change the color of an element. Here’s how to do it.

First, find the element that you want to change the color of. In our example, we’ll use the button element with the id of “change-color-button”:

var button = element(by.id(‘change-color-button’));

Next, use the button’s .getCssValue() method to retrieve the current value of the “color” CSS property:

var currentColor = button.getCssValue(‘color’);

Now, you can use the .executeScript() method to run a JavaScript snippet that will change the value of the “color” CSS property:

browser.executeScript(“arguments[0].style.color = ‘red'”, button);

You can also use this technique to change the value of other CSS properties, such as “background-color” or “font-size”.
