Matching groups

• match[0] hex value with hash - #f3f3f3
• match[1] hex value without the hash - f3f3f3

Example

hexColorRegex().exec('foo #fff bar')
//=> [ '#fff', 'fff', index: 4, input: 'foo #fff bar' ]

hexColorRegex({strict: true}).exec('foo #fff bar')
//=> null

hexColorRegex().exec('foo #f3f3f3 bar')
//=> [ '#f3f3f3', 'f3f3f3', index: 4, input: 'foo #f3f3f3 bar' ]

hexColorRegex({strict: true}).exec('foo #f3f3f3 bar')
//=> null
