browserAction.getBadgeTextColor()

Gets the text color for the browser action's badge.

From Firefox 63, unless the badge text color is explicitly set using browserAction.setBadgeTextColor(), then the badge text color will be automatically set to black or white so as to maximize contrast with the specified badge background color. For example, if you set the badge background color to white, the default badge text color will be set to black, and vice versa.

Other browsers always use a white text color.

This is an asynchronous function that returns a Promise.

Log the badge's text color:

function onGot(color) {

}

function onFailure(error) {
  console.log(error);
}

browser.browserAction.getBadgeTextColor({}).then(onGot, onFailure);
