Welcome to TVPaint Community forums !

Hello,

I was wondering, if you can have a brush in TVP so that the more pen pressure you apply the more the A color shifts to the B color?
(something like the "color dynamics" in Photoshop)

you can with the custombrush.

you need to make a black and white animbrush that animates (in say 255 steps (or frames)) from white to black
Set color mode to "luma stamp", white will channel A color and black will channel B color
(or luma invert stamp to switch this)
then set the anim connection to pressure.
fertig

That's it !

Thank you Peter!!!
