Gravity Forms Submit Button Colour and Required Field "*" Colour

Howdy,

I'd like to change the hover colour of the gravity form buttons on the home page (newsletter form) and contact page form to #d54b1a.

Also I would like to change the colour of the star "*" used for the required fields on both forms. I tried this but it didn't work:

/*Gravity Forms Required Star Colour */
.gform_wrapper .gfield_required {
color: #f2a502;
}

Thanks,
Casper
