Wallace Line Line. Wallace Line The Wallace Line or Wallace's Line is a faunal boundary line drawn in 1859 by the British naturalist Alfred Russel Wallace and named by English biologist Thomas Henry Huxley, that separates the ecozones of Asia and Wallacea, a transitional zone between Asia and Australia. West of the line are found organisms related to Asiatic species; to the east, a mixture of species of Asian and Australian origin is present. Wallace noticed this clear division during his travels through the East Indies in the 19th century. The line runs through Indonesia, between Borneo and Sulawesi (Celebes), and through
Line of purples absent from the gamut of sRGB. Magenta ink, which is one of CMYK's primaries, is also very distant from the Line for the reason explained above. The wide-gamut RGB color space approximates the colors on the Line better, but devices capable of displaying colors with this enhanced system are prohibitively expensive for ordinary consumers. Most of the names of the purple colors in the table below do not denominate colors on the line of purples, but instead are slightly less than maximally colorful, i. e. saturated. Line of purples In color theory, the line of purples or purple boundary is
