Colocar Colores a los Botones de Odoo

Puede que en determinado momento necesitemos colocar diferentes colores a los botones de Odoo para eso usaremos las clases de bootstrap.

<!-- Standard button -->
<button type="button" class="btn btn-default">Default</button>

<!-- Provides extra visual weight and identifies the primary action in a set of buttons -->
<button type="button" class="btn btn-primary">Primary</button>

<!-- Indicates a successful or positive action -->
<button type="button" class="btn btn-success">Success</button>

<!-- Contextual button for informational alert messages -->
<button type="button" class="btn btn-info">Info</button>

<!-- Indicates caution should be taken with this action -->
<button type="button" class="btn btn-warning">Warning</button>

<!-- Indicates a dangerous or potentially negative action -->
<button type="button" class="btn btn-danger">Danger</button>

<!-- Deemphasize a button by making it look like a link while maintaining button behavior -->
<button type="button" class="btn btn-link">Link</button>

Y en Odoo sería Así, donde en class definimos el color que queremos colocarle

 <button name="action_accepted_sii" type="object" string="Aceptar SII"
                                    class="btn btn-success" groups="account.group_account_invoice"
                                    attrs="{'invisible': [('offline','=',False)]}"/>
