How to map RGB channels on faders ?

[square]

Hi guys !
I would like to ask you if it is possible to map separately R & G & B channel on faders of my controller. What I am going to do is - to pull out eg. "green fader" and then the whole output is coloured to green.
Of course, i used search, but i didnt find an answer. Hope you understood me.
Thanks a lot for your responses

You can use the "colorize" effect on the composition level for that. In that effect you can map parametes to your faders.

I would go for Add/Subtract if you want RGB control

I use the add/subtract effect (on the layer usually) and either map the attributes to encoders on a midi controller or via ArtNet to the lighting desk so the Lampy can affect my video choices.
