A Blender node uses the Blending value to pick Input_1 or Input_2 or some value in between. When the Blending value is 0 or less, it is all Input_1. When the Blending value is 1 or more, it is all Input_2.
When you connect a node, the Blending value is the number in the Blender's Blending value multiplied with whatever is plugged in. (This is true of any node parameter. A number is multiplied with the attached node. A color chip is multiplied with the attached node.)
Using the connected button mask, this means that Input_1 is the cloth color. I selected a light blue. Input_2 is the button color. I selected RGB 239, 239, 239. Try different colors to convince yourself of how this works.
I now have achieved what you originally asked. Notice that there is no inversion of the mask necessary ... yet.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
