Android resource linking failed '@colors/blue' is incompatible with attribute resource (attr) reference.
I'm trying to set a custom color to the firebase push notification icon. This is the portion of my config.xml that is giving me incompatibility error.

</platform>
And this is the corresponding portion of my AndroidManifest.xml
<meta-data android:name="com.google.firebase.messaging.default_notification_color" android:resource="@colors/blue" />
And the full route for the colors.xml file is:
resources/android/xml/colors.xml
The target generated route is:
app/src/main/res/xml/colors.xml
And finally the colors.xml file code:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="blue">#38a8ff</color>
</resources>
Thank you
