[REQ] Navigation bouys in SH5

[Zedi]

Very confusing. Seems like this system is not universal and was not valid in ww2.

These lights and marks are prescribed across the world by the International Association of Lighthouse Authorities (IALA). In 1977 this IALA endorsed two maritime buoyage systems putting an end to the 30 odd systems existing at that time. Region A - IALA A covers all of Europe and most of the rest of the world, whereas region B - IALA B covers only the Americas, Japan, the Philippines and Korea. Fortunately, the differences between these two systems are few. The most striking difference is the direction of buoyage.

Quoting from this site:

Generally speaking, green markers are kept to the RIGHT when leaving a harbor and red markers are kept to the RIGHT when returning to harbor, thus coining the phrase, "Red, Right , Returning".

So that means.. I have red light on my right side when I enter in port and green when I leave it. Im a total noob regarding these stuff, so someone with sailing experience pls clarify these things.
