You can observe a colorless gas indirectly through its effects or reactions. For instance, you might notice changes in the environment, such as the formation of bubbles, changes in temperature, or a shift in pH when the gas interacts with other substances. Additionally, using specific detectors, sensors, or chemical indicators can help visualize the presence of the gas. Examples include using litmus paper to detect carbon dioxide or a flame test for hydrogen.
Colourless, or slightly white
Methane is a colourless, flammable gas that is the main component of natural gas.
Helium is a light colourless gas that does not burn
Colourless is a property, or word to describe matter, however the "gas" would be something you're describing. However, if a reaction is omitting a colourless gas, it could be considered a physical property of the reaction.
