Clathrus ruber of the mature fruit bodies have been identified as carotenes, predominantly lycopene and "beta"-carotene—the same compounds responsible for the red and orange colors of tomatoes and carrots, respectively. Lycopene is also the main pigment in the closely related fungus "Clathrus archeri", while "beta"-carotene is the predominant pigment in the Phallaceae species "Mutinus caninus", "M. ravenelii", and "M. elegans". Clathrus ruber Clathrus ruber is a species of fungus in the stinkhorn family, and the type species of the genus "Clathrus". It is commonly known as the latticed stinkhorn, the basket stinkhorn, or the red cage, alluding to the striking fruit bodies
Pigment discovery in the 1930s. In much of Europe, phthalocyanine blue is better known as Helio Blue, or by a proprietary name such as Winsor Blue. An American paint manufacturer, Grumbacher, registered an alternate spelling (Thanos Blue) as a trademark. Colour Index International resolves all these conflicting historic, generic, and proprietary names so that manufacturers and consumers can identify the pigment (or dye) used in a particular color product. In the CII, all phthalocyanine blue pigments are designated by a generic color index number as either PB15 or PB16, short for pigment blue 15 and pigment blue 16; these two numbers
