paag:palette_swap_color_cycling

[{{ paag_palette_effect_color_cycling.gif|a) active cycle entry, b) swap operation, c) in-place cycle}}]
**Color Cycling** refers to a [[Palette Swap]] effect where one or more entries in a [[palette]] are sequentially swapped with an active entry from another (or the same) palette.

The active entry/index in the other palette is increased or decreased periodically and wraps around to the other end when it goes out of range: it "cycles" across a range.

The cycle for indices 7,8,9,A in the example here could also be implemented in-place.
