The mark consists of a brown green shade such that by its transmission curve (measurement of factor of regular transmission under 0 degree incidence) it is obtained in the CIE 1931 system for lighting C, a dominant wavelength comprised between 575 and 577 nanometers, a purity superior to 90%, the Y component being comprised between 10 and 40. A characteristic point of this shade obtained for a thickness of 5 mm is determined by the following trichromatic co-ordinates x = 0,4744; y = 0,5030 with a dominant wavelength of 575,8 nanometers, the luminance Y being 20,8.
The drawing is lined for the color green and no claim to the shape of the bottle is made.
