Feature Request: Customizeable colors for charts

[bkuhl]

We're making a lot of use of dashboards. One thing that would make it much easier on the eyes is to be able to customize the color. For us, we like to have a specific color for different entities. So anything that shows users would be a certain shade of purple, anything that shows sales would be green, etc. It would be wonderful if we were able to customize the CSS class applied to different metrics/charts rather than it being hard coded like below:

      <div
        v-if="icon"
        class="rounded-lg bg-primary-500 text-white h-14 w-14 flex items-center justify-center"
      >
        <Icon :type="icon" width="24" height="24" />
      </div>

Being able to customize the CSS coloring while defaulting to bg-primary-500 as done here would be ideal.
