Select multiple rgb values with and and not or

[Jeremy5909]

Lets say I wanted to make some fog atom that fades away slowly and I want it to go from white->grey->black. If I do
rgb(0-255,0-255,0-255) to that same thing with the hexagon subtracting, it will do it for every color possible. How can I limit it to only 0-255,0-255,0-255 only when its together and not individual if that makes sense. Sorry I am not good with words but I hope it makes sense.

You could just put all the monochrome cells into a bundle. It's pretty inefficient, but it's all we have for now.
