I wasn't sure whether you were giving me an example or the exact line I 
needed.  The above gives:

X Error of failed request:  BadName (named color or font does not exist)
  Major opcode of failed request:  150 (RANDR)
  Minor opcode of failed request:  16 (RRCreateMode)Thanks
  Serial number of failed request:  31
  Current serial number in output stream:  31
