Per the documentation here: https://material.angular.io/components/tooltip/api

And the spec: https://github.com/angular/material2/blob/master/src/lib/tooltip/tooltip.spec.ts

You can set the property 'matTooltipClass', as follows:

  Show tooltip

Then in your CSS (global - not for the component):

  .mat-tooltip.tooltip {
    background-color: darkblue;
    font-size: 12px;
  }

Also see their demo here: https://github.com/angular/material2/tree/master/src/demo-app/tooltip

Also keep in mind if you are using SASS, that the container for the tooltip is at the bottom and nowhere near where you are placing it in your component's HTML, so do not nest it in that component. Make sure it is standalone, otherwise it will not work. This note applies as well obviously to the comment above if you just choose to override .mat-tooltip

To see the changes, in developer tools, find the div at the bottom with the class "cdk-overlay-container". Then hover over the element. You can use your arrow keys to navigate into the element while you are hovered over to confirm whether your class is being added.
