Change font color on Signature Block

The Smooth Signature widget has a small "Clear" option at the bottom right of the form.  It is getting lost in the background image.  I tried using some CSS and HTML font tags to change the color to something more visible, but have been unable to make this work.

Can you assist?

If you open the signature wizard and under the CUSTOM CSS tab you enter the following code

.clearButton {

color: blue !important;

}

You will be able to change the color of the link "CLEAR"
