Channel Mix to Buttons

Hi all,

I’m trying to colour an image in three sections with individual channel mixes. Is there anyway you can link a button to alter the values of these mixes? ie green button, blue and so on.

I also want to add the ability to select which part you colour, could this be done with a switch into the buttons to choose which chmix it’s editing?

Thanks

probably best if you start with this tutorial:

which will explain how to connect almost anything (buttons for instance) to anything (nodes for instance)

let me know if you have any further questions after that
