it's possible to make conditions with Vue to change add class according to the text loaded on the doom?

I have a list with colors name

<span>yellow</span>
<span>red</span>
<span>grey</span>

I want to make a condition for example if the name text is yellow I want to add class "color_yellow" and so on

Try like following snippet:

new Vue({
  el: '#demo',
  data() {
    return {
      colors: ['yellow', 'red', 'grey']
    }
  }
})

Vue.config.productionTip = false
Vue.config.devtools = false

.color_yellow {
  color: yellow;
}
.color_red {
  color: red;
}
.color_grey {
  color: grey;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="demo">
  <ul>
    <li v-for="(color, i) in colors" :key="i">
      <span :class="`color_${color}`">{{ color }}</span>
    </li>
</div>

<iframe name="sif1" sandbox="allow-forms allow-modals allow-scripts" frameborder="0"></iframe>

You may try this

<span :class="color.colorName">{{ color.colorName }}</span>

In css,

.yellow { color: yellow }
.red { color: red }
