#### Palette

-- Plot option: palette [palette, [<palette_1>], ..., [<palette_n>]] -- Plot option: palette [palette, <false>] It can consist of one palette or a list of several palettes. Each palette is a list with a keyword followed by four numbers. The first three numbers, which must be between 0 and 1, define the hue, saturation and value of a basic color to be assigned to the minimum value of z. The keyword specifies which of the three attributes (hue, saturation or value) will be increased according to the values of z. The last number indicates the increase corresponding to the maximum value of z. That last number can be bigger than 1 or negative; the corresponding values of the modified attribute will be rounded modulo 1.

Gnuplot only uses the first palette in the list; xmaxima will use the palettes in the list sequentially, when several surfaces are plotted together; if the number of palettes is exhausted, they will be repeated sequentially.

The color of the mesh lines will be given by the option `mesh_lines_color`. If `palette` is given the value `false`, the surfaces will not be shaded but represented with a mesh of curves only. In that case, the colors of the lines will be determined by the option `color`.

Default value: [hue, 0.25, 0.7, 0.8, 0.5], [hue, 0.65, 0.8, 0.9, 0.55], [hue, 0.55, 0.8, 0.9, 0.4], [hue, 0.95, 0.7, 0.8, 0.5]

There are also some inexact matches for `palette`. Try `?? palette` to see them.
