which specifier in sscanf - saffierr - 31.03.2015

I went through the whole sscanf specifiers, and I just could not get which one I had to use, or not even.
The code is /setcolor
PHP код:
CMD:setcolor(playerid, params[])
{
   if(IsPlayerAdmin(playerid))
   {
       SetPlayerColor(playerid, COLOR_BLUE);
       SendClientMessage(playerid, COLOR_LIME, "You have set your colour.");
   }
       else
   {
       SendClientMessage(playerid, -1, "SERVER: Unknown command.");
   }
   return 1;
} 
It is just, when you type /setcolor it will turn MY color to blue. But How do I make it so, that if I type /setcolor it will display a message /setcolor [ID] [COLOR]. I didn't know which specifier I had to use in sscanf.

u for user, h or x for a hexadecimal number. Although requesting raw hex colors isn't very user friendly. I would recommend letting the user choose from a list or preparing a pallet of swatches to choose from. Perhaps still keeping the raw input as a fallback.

I update my code, it now uses an SSCANF (k)custom specifier. You can add more colors to the list if you like.

Yo Crayder it's really really high appreciated bro, I just get the Last part, I don't get the SSCANF part. I hope you could explain me that, through PM.
Thanks!!!

Yeah I read that, but I just don't understand how to use it.
