Colors for Boulder's

[Kal-El]

The boulders take on the color of the rock they are on Edit: sorry this is incorrect it should be the block not the rock.

These resources when generated take the colour of the block below, so arent directly driven by the world palette; to change them immediately when changing the colours the server would have to scan the entire world for all such blocks to update the actual block colours individually)
