When the progress bar is starting from 30 seconds and reaching 10 seconds then it has a blue color. After reaching 10 seconds it’s changing color to orange with some shades. After crossing 5 seconds it changes the color of the progress bar to red for showing the danger. The red color is there because it’s near to ending.
