Nice, I've just seen the Variations are also available on the Blacksmith Forge, very nice touch

Thank you :)

Brown shades were planned, but would have resulted in 10 swatches on one mod. Five was already insane enough. I will probably still do that at some point, but it will be a separate mod when it happens.

You will note that clay brick patterns were not included - this is because they have a brown overlay that can't be changed so the grey would not be possible.

But speaking of clay brick - it will be getting an update in the near future as I have found a different method of making the small brick and can apply it to the missing items. Additionally the new items like heat sources and production stations will get added to the clay mod. Honestly I just didn't think about them when I was making that mod originally.
