Gray Scale effect in Placid Slider is done using CSS only and that’s why you do not need to upload two different images. There is an option on Placid Slider settings page to enable Grayscale on the same image using CSS. In the above demo, we have disabled that option and that’s why there is no Grayscale effect on the images.
