Several people have asked about the color of the Grand Bois "Cerf blue" and "Cerf green" tires. They have tan sidewalls and black tread, like traditional tires. The "blue" and "green" is just the color of the label. Initially, there was to be only a 28 mm Cerf tire, and when the 26 mm was added, the label color was used to distinguish them.
