How to add different styles to the data rendered with v-for in Vue?

for example:
< tr vmurfort = "item in Data" >

<td class="red">{{item.td}}</td>

< / tr >

Data = [td:12,td:14]
what if I want to add a separate red style for td > 13?

<tr v-for="item in Data">
  <td :class="{ red: item.td>13 }">{{item.td}}</td>
</tr>

v-bind:class {'red':item.td > 13}
