change laravel blade css class by the amount of objects

first of all, the question is not about the solution, but about the best practice.

my blade is:

@if (!empty($amount))
     <div class="amount ">
          
     </div>
@endif

color class is defined in service by amount. But I can bet, that is bad architectural solution.

So I need an advice about best practice in laravel for customizing blade class.
