Navigational warnings typically use a system of colors to convey specific messages. The primary colors include red, which indicates danger or a stop signal; yellow, which signals caution; and green, which indicates safe passage or go ahead. Additionally, blue may be used for information purposes, while white is often associated with navigational aids or safe waters. These colors help mariners quickly assess their surroundings and make informed decisions.
Mooring buoys come in all shapes, sizes and colors (other than those colors used for navigational aids).
Warning colors prevent some animals from being eaten because their bright colors serve as a warning. The colors signify to predators that eating the animal will cause them to become ill or hurt.

A warning color is a color that an animal uses to warn enemies that it is not safe to eat. Most animals that use color as a defence attempt to blend into their environment as much as possible (camouflage). Warning colors are the opposite. Animals displaying warning colors are bright and stand out. They are sending the message 'look at me, I don't need to hide from you because I know you can't hurt me.' Most animals display these warning colors to declare that they are poisonous and should never be eaten. Some animals display bright colors that appear to be warning colors, yet they are not poisonous. These are imitators - by pretending to be poisonous they can often deter most predators without going to the effort of producing venom.
Navigational charts show meteorological and hydrographic and navigational conditions.
Warning colors are typically bright and eye-catching, such as red, orange, and yellow. These colors are used in signs, symbols, and signals to alert people to potential hazards or dangers, prompting them to exercise caution or take necessary actions. The high visibility of warning colors helps to quickly communicate potential risks and prevent accidents.

This street map is a very handy navigational aid. This channel buoy is the navigational aid that saved my life!
US standard traffic warning signs are yellow background with black symbols or letters. Traffic warning signs in other countries are generally white or yellow background with a red or black border in a triangular shape. Industrial warning signs are various colors, including OSHA and ANZI standards with orange background and black lettering. A yellow OSHA or ANZI sign would mean "caution" not "warning".
