Ultimate 64 Color Palette
-------------------------

Starting from U64 core version 1.41, which comes with application firmware 3.10, the color palette has become programmable. The definition of the color palette tales place through a file with RGB values. It follows the standard that has been implemented for VICE as well, by means of .VPL files.

Loading a Palette
=================
As with many other file types, VPL files are recognized as palette files in the file browser. The context menu of a VPL file shows that it can be loaded as a palette, by showing "Apply Palette":

.. image:: ../media/config/apply_palette.png

When using the second option, "Set as Default", the VPL file will be copied to the **/flash/data** directory. The filename -- truncated if necessary -- will be stored into the configuration. Once the VPL files are in the **/flash/data** directory, they can be selected in the configuration menu (F2), under "U64 Specific Settings":

.. image:: ../media/config/cfg_palette.png

File Format
===========
A VPL file consists of 16 valid lines with color data. Empty lines, or lines that start with '#' are ignored. A valid line has three HEX values, separated by a space. A forth value, the dither value, which is defined in VICE has no effect on the U64. Note that the lines are in the order of the Commodore color codes, thus starting with black, then white, red, cyan, and so forth. An example of a VPL file is::
