Best method for palette swapping of animated sprites?

[Lbones-ai]

I was looking for palette swapping methods and I stumbled upon this:
replaceColor(Color:FlxColor, NewColor:FlxColor, FetchPositions:Bool = false):Array<FlxPoint>

Replaces all pixels with specified Color with NewColor pixels. WARNING: very expensive (especially on big graphics) as it iterates over every single pixel.

I also found out about palette swapping via openFL shaders but I'm guessing is the same thing performance wise because in the API it says:

Avoid changing it frequently as this is a costly operation.

There are better ways to do this?

Shaders should perform fine. The comment refers to changing the shader instance that's assigned to the sprite, which you shouldn't need to do.

Thanks, I should start get cracking with shaders then
