How to style a buttons in material-ui - material-ui

Question

Hi I want to style three buttons with different colors but When those buttons are disabled the custom style I've added at the beginning overrides the default style disabledTextColor, which adds a default fade and transparency value, so users can see that the button is disabled. How can style the disabled state or which should be the correct way to style the labelStyle and/or disabledTextColor? Here is an example
const style = {
labelStyle: {
color: 'red;
}
}
<FlatButton
label='Mit Linkedin anmelden'
labelPosition='after'
icon={<LinkedinIcon />}
onClick={() => Meteor.loginWithLinkedin()}
disabled={true}
labelStyle={style.labelStyle}
/>
</div>
<div className='mdl-cell mdl-cell--12-col'>
<FlatButton
label='Mit Google anmelden'
labelPosition='after'
icon={<GoogleIcon />}
onClick={() => Meteor.loginWithGoogle()}
disabled={true}
labelStyle={style.labelStyle}
/>
</div>
in this case the button always stays red even though the disabled state in True

You can create a little wrapper component around FlatButton that conditionally fades the labelStyle when the button is disabled.
const CustomFlatButton = (props) => (
<FlatButton
{...props}
labelStyle={{ ...props.labelStyle, opacity: props.disabled ? 0.3 : 1 }}
/>
);
...
<CustomFlatButton label="Disabled Red" style={{ color: 'red' }} disabled />
