Colors of Login Customizer

I am using the login customizer of the theme. For some reason not all the colors change. The background and the letters yes, but not the color of the letters of the log in button and neither the borders around the text boxes. They stay blue as in the original version. How can I change this? I have ticked all the boxes for another color but still they stay blue.
