Change background color in vue.js based on a class name

Question

New to vue.js and am wondering if this is a possible outcome. I have 8 different options of a background color that I want to render based on the given class name. I can achieve this with css but was wondering if there is a dynamic way with vue to accomplish this. my ideal outcome would be just change the class name in the markup and it will then render that associated bg color.

HTML:

<div class="page-header__container" :style="{ background: color }">
    <div class="container">
      <div class="row">
        <div class="page-header">
          <h1 class="page-header__text">
            Page Header Lorem ipsUm
          </h1>
</div>

js:

export default {
   name: 'Header',
   data() {
   return {
   color: '#333'
    };
   }
 };

css:

bg-one{
background-color: #673AB7
}
bg-two{
background-color: #7293A0
}
bg-three{
background-color: #45B69C
}

if u want to apply any css class declarated just have to bind the class and not style, i mean :class="color" — Christian Carrillo
