Change attribute for the File Rule

[thecyrilcril]

I have a file rule these

 'products.*.color.*.image' => File::types(['pdf', 'jpg', 'jpeg', 'png'])
   ->min(100)
   ->max(2 * 1024)

I'm trying to change the attribute to product color like so

public function attributes()
{
 return [
  ...
  'products.*.color.*.image'  => 'product color'
 ]
}

but its does not work, anyone know how?

For now I have reverted to specifying the rules like so

[
 'mimes:pdf,jpg,jpeg,png',
 'min:100',
 'max:2048',
]
