The ribbon color for diabetes awareness is gray, according to Disabled World. While the gray diabetes ribbon is still being used, the International Diabetes Federation has designated a blue circle named the Blue Diabetes Circle Awareness as a more commonly used symbol for diabetes awareness as of March 2015.
Awareness ribbons consist of short ribbon pieces folded into a loop as a way to represent or support different issues, diseases and causes by making a statement, claims Disabled World. They are widely used in the United States of America, Canada, U.K., Australia and several other parts of the world. One of the most well-known awareness ribbon colors is pink in support of breast cancer.
