I am working on a filmy looking preset and it ends up giving me issues such as seen above.
I managed to trace it back to the fact that I was tweaking the colour chanels and had a bunch of negative values.

is there any way to avoid this happening?

When switching off the channel mixer you got 100% red and about 50% green and 50% blue values there.

Now in the channel mixer your G and B channels are lowered by a significant amount, using the red channel values. On that particular part, since R channel is 100% it will lower those values the most. In this case down to 0%, leaving only a saturated red patch (R100 G0 B0).

I guess you can only avoid this by dialing it back a little or compensate by boosting the G and B channels somehow.

I have done some work on it and came up with a similar edit without negative values.

Anyone have a better solution to avoid 0% pixels? :frowning:
