@fede3110 You can achieve this by using the options parameter in the launch method. For example the following options can be configured before calling launch ImmersiveReader.launchAsync()
I believe the speed is set in the ReadAloudOptions() but the color options vary and are part of the CookiePolicy options. If you plan to disable the cookie policy then the colors will be set to default.
const options = {
readAloudOptions: {
speed: 1.5,
autoplay: true
}
};
ImmersiveReader.launchAsync(YOUR_TOKEN, YOUR_SUBDOMAIN, YOUR_DATA, options);
