Calculating values from string

I have an input string "BEA4F1" into which is encoded the following printer colour settings.

10 bits are colour intensity (0 to 1023)
10 bits are colour range ( 0 to 1023)
4 bits are for colour (0 to 15)

So an example message would be  "BEA4F1"
         
         intensity = 762 = 1011111010
         range     = 591 = 1001001111
         colour    = 1   = 0001
         
         So binary (24 bits = 1011 1110 1010 0100 1111 0001 = "BEA4F1"
         
         how do I get intensity, range and colour values back from string "BEA4F1"?
         
         Thanks

Code below to get them back in binary
string x = hex2binary("BEA4F1");

            string intensity = x.Substring(0,10);
            string range = x.Substring(10,10);
            string colour = x.Substring(20, 4);

        static string hex2binary(string hexvalue)
        {  
            string binaryval = "";  
            binaryval = Convert.ToString(Convert.ToInt32(hexvalue, 16), 2);
            return binaryval;
        }

Also added the convertion to integer-values
static void Main(string[] args)
        {
            string x = hex2binary("BEA4F1");

            string sIntensity = x.Substring(0,10);            
            string sRange = x.Substring(10,10);            
            string sColour = x.Substring(20, 4);

            int intensity = Convert.ToInt32(sIntensity, 2);
            int range = Convert.ToInt32(sRange, 2);
            int colour = Convert.ToInt32(sColour, 2);

        }

        static string hex2binary(string hexvalue)
        {  
            string binaryval = "";  
            binaryval = Convert.ToString(Convert.ToInt32(hexvalue, 16), 2);
            return binaryval;
        }
