clear graphic effects is a command block and a looks block. It reverts all the graphic effects amounts to 0.
clear graphic effects::looks
One of the workarounds is to revert each effect manually, but this is slow and time-consuming to build the script.
set [color v] effect to (0) set [saturation v] effect to (0) set [brightness v] effect to (0) set [ghost v] effect to (0) set [fisheye v] effect to (0) set [whirl v] effect to (0) set [pixelate v] effect to (0) set [mosaic v] effect to (0) set [negative v] effect to (0)
Another workaround is to loop through each graphic effect:
for each ((effect)::list) in (list[color][saturation][brightness][ghost][fisheye][whirl][pixelate][mosaic][negative]@delInput@addInput::list) { run ({set [ v] effect to (0)} @addInput) with inputs (effect) @delInput @addInput::control } @loopArrow::list
