George button to make any pure rgb color to black ?

[Nhils]

Hi !

I love to animate with as few layers as possible, for my sanity, and I tend to work with pure RGB colors : I start roughing in green, tie down in blue, clean in black, and so on.

I love the buttons that let me repaint a part of my drawing in another color etc, but sometimes I wish I had a button that would turn all my pixels with pure green color into pure black, without messing with the blue ones ? Like if I have several colors on my instance, like part rough in green some areas tied down in blue, I with I could turn the blue ones into black with the greens untouched.

I don't know how to go about doing such a thing ? I wouldn't know which command to use.
I couldn't find the doc for the tv_pixelmatrix command, and I'm not sure if that would be the one.

Maybe the image is more explicit about what I'm trying to do:

If anyone knows which george command would be useful, I can try to work from there

Thank you!

you'd have to script something where it would:
first duplicate the layer
then on the top layer:
- kill al except blue,
- turn al remaining color (the blue) to black
then on bottom layer:
-kill blue
finally merge back the two layers into one.

but i can't help with scripting.


why not use the FXstack>replace color?
in this image you see in the splitscreen preview what it does to blue...

Reacting a bit late but I ended up going this route

I created bins of the color replacer for each color, and assigned them to buttons. A bit tedious, as each option had to account for several colors, but it worked in the end:

I just end up checking the color I'm interested in and apply to the frames that need it.
