Which buoy color indicates the starboard side of a channel in Region A?

In Region A of the IALA Maritime Buoyage System, the color that indicates the starboard side of a channel is red. This is vital for navigation, as it allows mariners to clearly identify the correct side of the channel when traveling in a designated direction, typically when entering from the sea. The use of red for the starboard side aligns with international maritime standards, ensuring consistency and safety for vessels in different regions of the world. This helps prevent confusion and promotes safe navigation through channels by providing a clear visual cue for vessel operators.
