I also did additional color correction improvements for acid pipes with green "streaks" instead of rust...

I did all these color corrections for the mod https://mods.factorio.com/mod/call-plumber/discussion/6754ece8eef1dc1b03495d17
But unfortunately, the author of this mod behaved a little strangely and I could not find a common language with him.
All these color corrections were made by me personally. Therefore, if you want, you can use them without restrictions.
