Beni Kumonryu are a rare form of Kumonryu, they have red along with the black and white. They are scaless and their pattern actually changes throughout the year. No one is absolutely sure what causes the color change, but the two best theories are a change in temperature or a change in pH. Beni Kumonryu are usually black in the winter. The white and red usually appears in the spring and summer.
Young beni Kumonryu may show no black, this can develop as they mature.
