 Extends a 3-digit color code to a 6-digit color code.

+### detectDeviceType
+
+Detects wether the website is being opened in a mobile device or a desktop/laptop.
+
+Use a regular expression to test the `navigator.userAgent` property to figure out if the device is a mobile device or a desktop/laptop.
+
+```js
+const detectDeviceType = () => /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ? "Mobile" : "Desktop";
+// detectDeviceType() -> "Mobile"

+### negate
+
+Negates a predicate function.
+
+Take a predicate function and apply `not` to it with its arguments.
+
+```js
+const negate = func => (...args) => !fun(...args);
+// filter([1, 2, 3, 4, 5, 6], negate(isEven)) -> [1, 3, 5]
+// negate(isOdd)(1) -> false
