 **isHash(str, algorithm)**              | check if the string is a hash of type algorithm.<br/><br/>Algorithm is one of `['md4', 'md5', 'sha1', 'sha256', 'sha384', 'sha512', 'ripemd128', 'ripemd160', 'tiger128', 'tiger160', 'tiger192', 'crc32', 'crc32b']`
 **isHexadecimal(str)**                  | check if the string is a hexadecimal number.
 **isHexColor(str)**                     | check if the string is a hexadecimal color.
+**isRgbColor(str, [, includePercentValues])**                     | check if the string is a rgb or rgba color.<br/><br/>`includePercentValues` defaults to `true`. If you don't want to allow to set `rgb` or `rgba` values with percents, like `rgb(5%,5%,5%)`, or `rgba(90%,90%,90%,.3)`, then set it to false.
 **isIdentityCard(str [, locale])**      | check if the string is a valid identity card code.<br/><br/>`locale` is one of `['ES', 'zh-TW', 'he-IL']` OR `'any'`. If 'any' is used, function will check if any of the locals match.<br/><br/>Defaults to 'any'.
 **isIn(str, values)**                   | check if the string is in a array of allowed values.
 **isInt(str [, options])**              | check if the string is an integer.<br/><br/>`options` is an object which can contain the keys `min` and/or `max` to check the integer is within boundaries (e.g. `{ min: 10, max: 99 }`). `options` can also contain the key `allow_leading_zeroes`, which when set to false will disallow integer values with leading zeroes (e.g. `{ allow_leading_zeroes: false }`). Finally, `options` can contain the keys `gt` and/or `lt` which will enforce integers being greater than or less than, respectively, the value provided (e.g. `{gt: 1, lt: 4}` for a number between 1 and 4).
