How to change default color?

[nurzhannogerbek]

In default.js file I found this setting of color. How to change the color?

        <v-date-picker class='v-date-picker'
                       mode='range'
                       v-model='range'
                       :show-day-popover=false
                       :min-date='minDate'
                       :max-date='maxDate'
                       show-caps
                       :input-props='{placeholder: "", readonly: true}'
                       @dayclick='startClick'
                       @input='finishClick'>
        </v-date-picker>

Use 'tint-color' props
