Laravel Eloquent delete() not working

Sorry, I've figured out the problem. My mistake to post this question.

What I tried to do:

$color = new ProductColor();
$color->find($color_id);
$color->delete();

Should be:

$color = ProductColor::find( $color_id );
$color->delete();

My problem was that I was scared about the IDE complaining about using non-static method 'find'
