The utility method below can be used to convert an RGB color from hexadecimal format to integer format:

// Hexadecimal RGB Integer Method
// converts an RGB value from hexadecimal color format (#000000) to RGB integer format

// "#000000" format refers to hexadecimal color code
// "0x00000000" format refers to general hexadecimal number

// declare parameters
#DECLARE($rgbColorHex : Text)->$rgbInt : Integer

// declare variables
var $input; $output; $rgbHexNum : Text

// change from "#000000" to "0x00000000" format
$rgbHexNum:="0x00"+Replace string($rgbColorHex; "#"; "")

// insert into 4DTEXT transformation tag + process tag
$input:=""
PROCESS 4D TAGS($input; $output)

// convert resulting string to integer value
$rgbInt:=Num($output)

Here is an example code snippet using this method:

// Test Method

// declare variables
var $redHex; $customHex : Text
var $redInt; $customInt : Integer

// red color
$redHex:="#FF0000"
$redInt:=RGBHextToInt($redHex)

// custom color (lime green)
$customHex:="#8FFF42"
$customInt:=RGBHextToInt($customHex)
