You can build palettes from any of the system colors. Simply drag a system color over to an active slot on the palette.
If you change a system color, it will also update all of the palette colors that reference it.
It’s important to note that this will only happen in the color tool. If you change a color at runtime, you will need to manually update any referenced palette color. Likewise, you can rearrange system colors and it will have no effect on the palette colors. As long as the system color exists, it will be referenced correctly in the palette. If you delete a color, any palette that references it will be substituted for the first system color.
Finally, you can add more system colors, if the Color Chip allows, via the drop-down menu.
If you are out of system colors, you will get a warning asking you to increase the total color count in the data.json file.
Finally, in palette mode, system colors must be unique. If you attempt to create a new system color or edit one to a hex value that already exists you will get an error.
