@Mohammad yes the toggle operator is best used with list fields.
You can further simplify and skip the list widget:
<$vars
lightPalette="$:/palettes/Vanilla"
darkPalette="$:/palettes/SolarFlare"
>
<$button>Day/Night II
<$action-setfield $tiddler="$:/palette"
text={{{[{$:/palette}match<lightPalette>then<darkPalette>else<lightPalette>]}}}/>
</$button>
</$vars>
