Fala Henrique,

According to this image, this is the coloring order of your application:

There in his xml style. where you declare the colors, just add:

<item name="android:navigationBarColor">@color/theme_color</item>

Note: Note that this change is only valid from Lollipop (API 20) onwards.

Hugs.
