RNS:: Butterfly - Palette:
This feature lets you extend the number of colors available in System Color Palette.
To set up this feature, open the "Palette" screen in Butterfly.
Use the Palette Editor whenever standard set of 256 system colors (including the 24 black ones) doesn't contain a color that you wish to use for a User Interface element.
You can edit the last 24 System Color Palette items that are black by default.
On 8-bit display devices you have a choice of 4096 different colors, which is the maximum for these devices.
Palette Editor is useful and available only in the color display mode.
Having the RNS:: Butterfly Hack active ensures that your Palette will be automatically reloaded after each soft reset.
Although possible, do not modify any items assigned to the User Interface elements.
