Change Colour of submit button on click

I can change the static properties of the submit button using the below code.

When you press the submit button it fades to a lighter shade with the circle for when it's processing.

Is it possible to change the color of the "processing" submit button - i.e the lighter shade.

So green for unpressed - Red whilst the form processes?


#view_262 div{
padding: 100px !important;
background-color: Green !important;
color: white !important;
font-size: 100px !important;
font-weight: bold !important;
