+# React Native Animated Background Color View
+A modified React Native `View` component that animates it's `backgroundColor` when `color` prop changes. **Works on iOS & Android.**
+
+## Installation
+`npm install react-native-animated-background-color-view --save`
+
+## Usage
+Import **AnimatedBackgroundColorView** component
+
+```
+import { AnimatedBackgroundColorView } from 'react-native-animated-background-color-view';
+```
+
+Use as follows:
+
+```
+<AnimatedBackgroundColorView color='#00aced' />
+```
+Each time the `color` prop value changes the `backgroundColor` will use the [React Native timing animation](https://facebook.github.io/react-native/docs/animated.html#timing) to animate from the previous value to the current value.
+
+### Animate On Component Mount
+You can also specifiy an initial color for the background color to animate from when the component mounts:
+```
+<AnimatedBackgroundColorView
+    color='#00aced'
+    initialColor='red'
+/>
+```
+On mount the component `backgroundColor` will be `blue` and then animate to `#00aced`.
+
+### Using the `children` Prop
+The `AnimatedBackgroundColorView` component works just like the standard React Native `View` component.  `AnimatedBackgroundColorView` is designed to be nested inside other `View` components or other `AnimatedBackgroundColorView` components and can have 0 to many children of any type.
+
+```
+class AnimatedBackgroundColorViewWithText extends Component {
+    render = () => {
+        return (
+            <AnimatedBackgroundColorView
+                color='#00aced'
+                initialColor='red'
+            >
+                <Text>Hello, world!</Text>
+            </AnimatedBackgroundColorView>
+        );
+    }
+}
+```
+
+## Configuration
+You can configure `AnimatedBackgroundColorView` by passing the following props:
+
+* **color** (string, default: `'#00aced'`): the color value to which the component `backgroundColor` will animate
+* **delay** (number, default: `0`): the length in milliseconds the component will wait before animating to the next `color`
+* **duration** (number, default: `2400`): the length in milliseconds the timing animation will last
+* **easing** (React Native [Easing function](https://facebook.github.io/react-native/docs/easing.html), default: `Easing.out(Easing.exp)`): the easing function to define animation curve
+* **initialColor** (string, default: `null`): the color value from which the component `backgroundColor` will animate on mount
+* **style** (React Native [ViewPropTypes.style](https://facebook.github.io/react-native/docs/style.html)): additional styles applied to the component
