When I was a kid in Minnesota we needed to learn port/starboard and the colors red/green. A trick that helped me remember is that "LEFT", "PORT", and "RED" are all the shorter words and "RIGHT", "STARBOARD", and "GREEN" are the longer words in the respective pairs. FWIW.
For sailors, we learn "red-right-returning," which means to keep the red aids to navigation on the right (starboard) side when returning to port. Which is great, except when it doesn't apply--parts of Europe, Australia, a lot of Asia.
You'd think this would be a solved problem by now, but nope.
