How to add color to the act window domain tabs?

[finals_mvp (A.S)]

Hi,
How to add color to the domain tabs which shows the state?

    <record model="ir.action.act_window.domain" id="act_woven_label_draft">
        <field name="name">Draft</field>
        <field name="sequence" eval="10"/>
        <field name="domain" eval="[('approval_status', '=', 'draft')]" pyson="1"/>
        <field name="count" eval="True"/>
        <field name="act_window" ref="act_product_woven_label_template"/>
    </record>
    <record model="ir.action.act_window.domain" id="act_woven_label_sample_production">
        <field name="name">To Sample Production</field>
        <field name="sequence" eval="20"/>
        <field name="domain" eval="[('approval_status', '=', 'in_sample_production')]" pyson="1"/>
        <field name="count" eval="True"/>
        <field name="act_window" ref="act_product_woven_label_template"/>
    </record>

would be nice if I could add muted to Draft, and warning to the second domain tab.

Thanks in advance!

There is no such feature.
