**isHexColor(str)** | check if the string is a hexadecimal color.
**isHSL(str)** | check if the string is an HSL (hue, saturation, lightness, optional alpha) color based on [CSS Colors Level 4 specification](https://developer.mozilla.org/en-US/docs/Web/CSS/color_value).
Comma-separated format supported. Space-separated format supported with the exception of a few edge cases (ex: `hsl(200grad+.1%62%/1)`).
**isIBAN(str)** | check if a string is a IBAN (International Bank Account Number).
-**isIdentityCard(str [, locale])** | check if the string is a valid identity card code.
`locale` is one of `['PL', 'ES', 'IN', 'IT', 'IR', 'MZ', 'NO', 'TH', 'zh-TW', 'he-IL', 'ar-LY', 'ar-TN', 'zh-CN']` OR `'any'`. If 'any' is used, function will check if any of the locals match.
Defaults to 'any'.
+**isIdentityCard(str [, locale])** | check if the string is a valid identity card code.
`locale` is one of `['LK', 'PL', 'ES', 'IN', 'IT', 'IR', 'MZ', 'NO', 'TH', 'zh-TW', 'he-IL', 'ar-LY', 'ar-TN', 'zh-CN']` OR `'any'`. If 'any' is used, function will check if any of the locals match.
Defaults to 'any'.
**isIMEI(str [, options]))** | check if the string is a valid IMEI number. Imei should be of format `###############` or `##-######-######-#`.
`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 a array of allowed values.
**isInt(str [, options])** | check if the string is an integer.
`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).
