Change color of the Focus indicatior

I have a simple form that validates according to the Best
Practices in the Validation tutorial.

i.e. If there is a field that doesn't validate - show an
error, check input as they type and change the

indicator once the input validates. The thing is that if I
click on the input the focus ring is RED and

stays RED even after the validator passes.

appreciated.
