Text-color for v-tooltip

I have many v-tooltips components and I'd like to know a way to change the text-color of it, not the color of the tooltip. I tried inspecting the element but it's impossible to inspect the tooltip since it only appears on hover of the element.

Here's my code:

    <div v-if="this.nbFiltersActive !=0">
      <v-btn 
        v-if="this.toggleSettingsBtn == true"
        fab
        class="active-filters-alert"
        color="red"
        tile
        dark
        @click.stop="drawerSettings = true"
      >
        <v-tooltip 
          nudge-bottom="610"
          nudge-left="88"
          open-delay="500"
          color=#696969
        >
          <template #activator="{ on }">
            <span v-on="on" :color="textLightGrey">{{nbFiltersActive}}</span>
          </template>
          <span>You have filters applied</span>
        </v-tooltip>
      </v-btn>
    </div>

I also looked into the vuetify documentation but I didn't find any attribute for the text color on v-tooltip, only on the background-color.

Solution

You can try with css on .v-tooltip__content class:

new Vue({
  el: '#app',
  vuetify: new Vuetify(),
  data() {
    return {
    toggleSettingsBtn: true,
    nbFiltersActive: 421,
    textLightGrey: ''
    }
  }
})

.v-tooltip__content {
  color: blue !important;
}

      </template>
      <span>You have filters applied</span>
    </v-tooltip>
  </v-btn>
</div>
      </v-container>
    </v-main>
  </v-app>
