Come si modifica il seguente, affinchè possa impostare un colore anche per lo sfondo dei select ?

<style type="text/css">
<!--
body { background-color : #ffa040 ; font-size: 8pt; font-family:Arial; color: #470087;}
td { background-color : #ffc080 ; font-size: 16px; font-family:Arial; font-weight: regular; color: #470087;}



. { background-color : #ffc080 ; font-size: 16px; font-family:Arial; font-weight: regular; color: #470087;}

a:hover { background-color : #ffc080; font-family:Arial; font-weight: regular; color: #470087;}

a:active { background-color : #ffc080 ; font-family:Arial; font-weight: regular; color: #470087 ;}

</style>

Grazie
