active_callback on is_active_widget

Hello again (last time on github),
I’m posting here since it not an issue but a question.

I’m wondering, tried a lot, if it’s possible to use
is_active_widget(”, ”, ‘widget-ID’) as an active_callback ?
I’m just trying to hide a color control if a specific widget is not active.

Can’t use required since it’s not depending on other field(s) value(s),
and struggled a lot, with no result, to create a custom callback function
but i don’t know yet how to return an if statement in php to reproduce this example by using if(is_active_widget(”, ”, ‘widget-ID’))

function my_custom_callback() {
    return ( is_singular( 'recipe' ) ) ? true : false;
}

‘active_callback’ option

Thanks a lot in advance for your help.
