Colors
Included with Vuetify is the entire Material Design color library. These color classes drastically help the prototyping phase or make the need for additional color declaration not needed.

Classes

You can change a background or text color by adding a class to the element. For background, use just the name, for example, <div class="red">. To use a shade, just add the modifying type, such as, darken-3. Text is very similar, adding a modification class, red--text, you can change the color of text, or change the type with adding text--lighten-2. For some elements like the v-badge, you can use the --after type for the background, <span class="green--after" v-badge:5>.
These colors are also available as javascript variables, just import colors from 'vuetify/es5/util/colors'

Color Pack

Vuetify comes pre-built with a Material Design Color Pack (thanks Materialize.css) by default. While convenient, this also increases the css export size by ~30kb. This can be disabled in both the webpack and webpack-ssr Vue cli templates.
Webpack
Navigate to src/App.vue. Scroll to the style element and set $color-pack = false above the Vuetify css import.
Webpack-SSR
Navigate to src/stylus/main.styl. At the top of the file, declare $color-pack = false.
