Using ringing artifact to make luminance invisible* (+Chroma only* preset)

[333Ruslan333]

While I was tinkering with the ringing artifact, I noticed that from certain values luma turns into vertical lines. Also the more blurred the luminance channel is, the less visible lines become. It also allows to "extract" chrominance channel because ringing does not affect it.
Here are some examples.
Before:

After:
(White-gray lines)

2)

(Sort of invisible luma)

2)

(Chroma (luma is sligtly visible here))
1)

2)

I added some noise 'cause it looks cooler this way
