Never heard of THAT before. I think your information's wrong, or for one of the illegal shards we can't' discuss here.
It's 50% colored/50% Iron for Armor BODs (all weapons are Iron, so this works out to 25% colored armor/25% Iron Armor, 50% weapons) from 70 to 110 skill.
At 110, it goes to 70% colored Armor (35% colored Armor, 15% Iron Armor, 50% Weapons).
At 120, it goes to 90% colored Armor (45% colored Armor, 5% Iron Armor, 50% Weapons).
Race has never had ANYTHING to do with BODs - only to collecting resources (such as mining and lumberjacking)
