## Named palettes

- The current palette can be saved to a named colormap for future use. See set colormap.
- pm3d and image plots can specify a previously saved palette by name. This permits the use of multiple palettes in a single plot command. See colorspec palette.
- Named palette colormaps can be manipulated as arrays of 32-bit ARGB color values. This permits addition of alpha-channel values or other modifications not easily specified in a set palette command.
- There is a new predefined color scheme set palette viridis.
- Palettes read from a file or datablock (set palette file) may be specified either using fractional color components or 24-bit packed RGB values.
