The mark consists of a brown green shade such that its transmission curve (measurement of the factor of regular transmission under 0 degrees incidence) it is obtained in the CIE 1931 system for a light C, a dominant wavelength comprised between 575 and 577 nanometers, a purity superior to 90%, then Y components being comprised between 10 and 40. A characteristic point of this shade obtained for a thickness of is determined but the following trichromatic coordinates x= 0,4744; y=0,5030 with a dominant wavelength of 575,8 nanometers, the luminance Y being 20,8.
The color and the shape of the bottle are claimed as part of the mark.
