For an information like this, always check the wiki ROM map.
The two main sets are at $D2EC00 and $D2ED00. I'm not sure what the 2nd WOB / WOR sets do. If you only want to assign the WOR palette to the WOB, you can just write these instructions at $EE84C1 but the result might not be really nice since the two map do not use the same tileset:
Edit: For a simple replacement a second solution is copying with a hex editor the $D2ED00-$D2EDFF block to $D2EC00-$D2ECFF.
Code:
$D2EC00 $D2ECFF World of Balance Palettes (8 palettes, 16 colors each)
$D2ED00 $D2EDFF World of Ruin Palettes (8 palettes, 16 colors each)
$D2EE00 $D2EE1F Setzer's Airship Palette (16 colors)
$D2EE20 $D2EE3F Chocobo Palette (for world map, 16 colors)
$D2EE40 $D2EEFF Other WoB Palettes (16 colors each)
$D2EF00 $D2EF1F Falcon Palette (16 colors)
