Australian Plate south, is now being torn apart along the transform boundary marked by the Alpine Fault. South of New Zealand the boundary becomes a transitional transform-convergent boundary, the Macquarie Fault Zone, where the Australian Plate is beginning to subduct under the Pacific Plate along the Puysegur Trench. Extending southwest of this trench is the Macquarie Ridge. The southerly side is a divergent boundary with the Antarctic Plate called the Southeast Indian Ridge (SEIR). The subducting boundary through Indonesia is not parallel to the biogeographical Wallace line that separates the indigenous fauna of Asia from that of Australasia. The eastern islands of
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
