...
<item name="faceColor">@color/colorWhite</item>
<item name="gradeColor">@color/orange</item>
</style>To change the gradient color set, you can override the attributes in the GradientBackgroundView or in your theme.
<style name="YourCustomThemeTheme">
...
<item name="zeroGradeGradientColors">@array/garageZeroGradeGradientColors</item>
<item name="oneGradeGradientColors">@array/garageOneGradeGradientColors</item>
<item name="twoGradeGradientColors">@array/garageTwoGradeGradientColors</item>
<item name="threeGradeGradientColors">@array/garageThreeGradeGradientColors</item>
<item name="fourGradeGradientColors">@array/garageFourGradeGradientColors</item>
<item name="fiveGradeGradientColors">@array/garageFiveGradeGradientColors</item>
