Technically, the colours are just decorative - but if you want a game-friendly reason, it might be because the salt- and mineral-content there is different due to the cove bordering on the ILZ and having a few black smokers. Volcanic activty = rise in temperature = different bacteria, heightened bacterial growth, introduction of other minerals and bonding of salt to those other minerals, ... = different colour.
