You can use the same texture as the starting point… but at some point that will have to be duplicated enough times to accommodate the color steps you want to have.
… and each of those steps will be individual (copied) textures… albeit with different color shifts in the edit.
This is kind of the same thing with the components as well… Each Component is just a definition to tell SU how every instance of the component should look and they are all identical copies.
To get some level of independence you’ll have to work with nested components, and/or branch off to independent components which is what the ‘Make Unique’ Command does.
There may be some hope for this, in that somebody might have made a gradient tool which allows for incremented stepping in between two colors points. That would be great, but I haven’t seen such a thing yet. (maybe because I haven’t been looking ?).
So my take on this, is probably less than ideal… in that I think you have to approach this dealing with unique and independent sections in the model, and the individual textures that will be applied to them.
Subdivisions can be made with regular lines, and those lines can be hidden so the overall effect is of a singular board, with all of the color steps you want. But at the micro level these are all independent faces, and textures.
Luckily, I’m not the final word on this, and maybe others have come up with a better method.
