 **isHexColor(str [, options])**         | check if the string is a hexadecimal color. <br/><br/>`options` is an object that defaults to `{ require_hashtag: false }`.<br />Options: <br/> `require_hashtag`: Enforce # prefix, default false.
 **isHSL(str)**                          | check if the string is an HSL (hue, saturation, lightness, optional alpha) color based on [CSS Colors Level 4 specification][CSS Colors Level 4 Specification].<br/><br/>Comma-separated format supported. Space-separated format supported with the exception of a few edge cases (ex: `hsl(200grad+.1%62%/1)`).
 **isIBAN(str, [, options])**            | check if the string is an IBAN (International Bank Account Number).<br/><br/>`options` is an object which accepts two attributes: `whitelist`: where you can restrict IBAN codes you want to receive data from and `blacklist`: where you can remove some of the countries from the current list. For both you can use an array with the following values `['AD','AE','AL','AT','AZ','BA','BE','BG','BH','BR','BY','CH','CR','CY','CZ','DE','DK','DO','EE','EG','ES','FI','FO','FR','GB','GE','GI','GL','GR','GT','HR','HU','IE','IL','IQ','IR','IS','IT','JO','KW','KZ','LB','LC','LI','LT','LU','LV','MC','MD','ME','MK','MR','MT','MU','MZ','NL','NO','PK','PL','PS','PT','QA','RO','RS','SA','SC','SE','SI','SK','SM','SV','TL','TN','TR','UA','VA','VG','XK']`.
-**isIdentityCard(str [, locale])**      | check if the string is a valid identity card code.<br/><br/>`locale` is one of `['LK', 'PL', 'ES', 'FI', 'IN', 'IT', 'IR', 'MZ', 'NO', 'TH', 'zh-TW', 'he-IL', 'ar-LY', 'ar-TN', 'zh-CN', 'zh-HK', 'PK']` OR `'any'`. If 'any' is used, function will check if any of the locales match.<br/><br/>Defaults to 'any'.
+**isIdentityCard(str [, locale])**      | check if the string is a valid identity card code.<br/><br/>`locale` is one of `['LK', 'PL', 'ES', 'FI', 'IN', 'IT', 'IR', 'MZ', 'NL', 'NO', 'TH', 'zh-TW', 'he-IL', 'ar-LY', 'ar-TN', 'zh-CN', 'zh-HK', 'PK']` OR `'any'`. If 'any' is used, function will check if any of the locales match.<br/><br/>Defaults to 'any'.
 **isIMEI(str [, options]))**            | check if the string is a valid [IMEI number][IMEI]. IMEI should be of format `###############` or `##-######-######-#`.<br/><br/>`options` is an object which can contain the keys `allow_hyphens`. Defaults to first format. If `allow_hyphens` is set to true, the validator will validate the second format.
 **isIn(str, values)**                   | check if the string is in an 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).
