From the ratio of the red and green light amounts to the respective reference light amounts, V
The transmittance, the red light amount transmittance R, and the green light amount transmittance G are obtained, and a first predetermined value, a second predetermined value (where first predetermined value> second predetermined value), and a third predetermined value are obtained. When V transmittance ≧ first predetermined value, the color of the glass bottle (18) is made colorless, and when V transmittance <second predetermined value, the glass bottle (18) is defined as In the case where the color of 18) is black and the first predetermined value> V transmittance ≧ the second predetermined value, the ratio between the red light amount transmittance R−the green light amount transmittance G and the V transmittance or its corresponding value When H ≧ the third predetermined value, the color of the glass bottle (18) is set to brown, and when H <the third predetermined value, the color of the glass bottle (18) is set to green. Characteristic glass bottle color identification method.
