What color is methane?

Methane is a colorless gas that is the primary component of natural gas. It does not have any intrinsic color, which makes it challenging to detect by sight. This characteristic is significant, as it underlines the importance of monitoring and detection methods for safety reasons in environments where methane might be present. The colorless nature of methane means that other qualitatively distinct properties, such as its flammability and odorless state, are relied upon for identification and assessment of its presence. This further supports the basic understanding of methane's physical characteristics in both environmental science and industrial applications.
