The preferred color of ribbon for lung cancer awareness is clear or pearl, according to Disabled World. However, some organizations use other colors or symbols.
The clear or pearl colored ribbon is also used for awareness of lung disease, mesothelioma, emphysema and multiple sclerosis, states Disabled World. Awareness ribbons are short pieces of colored ribbons folded into a loop and used to make a statement to support a cause or an issue. The red ribbon is for support of those with acquired immunodeficiency disease (AIDS). The pink ribbon is for support of those with breast cancer. Many awareness ribbon colors have multiple associations.
