The 67 MY factory paint GM code 503 or 533 (as a two-tone) consisted of:
503 Light Green (Ditzler 53523 or Lucite 4728-L) exterior primary body color.
526 Ivory (Ditzler 8290 or Lucite 4195-L) was the two-tone roof color.
Please note the roof was painted only to but not including the drip rails in 67. This is unlike later years that extended down the front posts and door frames. There is an example picture below of the correct scheme though not the same color.
If you want to look about for matching codes from different paint mfg. this is a good place to start.
