I haven’t tested this yet from another post but if you read about how 3 stripe was originally made, you’ll logically determine the right tweaking from the channel effects.
“Apply a Set Channel filter to isolate individual channels.
Three seperate instances of the footage stacked using lumanance set channel. i only allowed one for green, one for red, and one for blue. then i tweaked the green a little towards yellow, the red a little towards magenta, and blue a lot towards cyan and blend them back together with channels combine. then you compress the midtones. i was very pleased with my results.”
