I'm playing Pyanodons right now, just wondering

The color coded pipes mod only makes color coded versions of the base game pipes, pump, and storage tank. As long as those base items and entities exist, the mod should work. It doesn't currently make color coded versions of other modded pipes, pumps, or storage tanks.
Support for K2 and SE pipes have already been requested, but I have no eta for when/if it will be possible.

The planner should work great with all the Pyanodons fluids though, just make sure to switch to "Perfect Match" mode in mod settings to have it use pipes that perfectly match the fluids (best guess mode currently only works for base game fluids).

Alright, thanks for this clarification. Nice mod anyhow.

Yeah I used your tool and it colored everything correctly even the modded stuff but then now I have to re-pipe my whole base because I realized you're using the vanilla pipe length and not what the mods we are using have (K2-SE). :(

Hmmm… thanks for letting me know. My mod adds the color coded versions of pipes in the data-updates stage with the hope that any changes to the base game pipes (such as underground length, storage capacity, etc.) will be captured. I’ll take a look at what K2SE is doing, the color coded versions are supposed to be functionally identical to the base game ones.

Also, in case you didn’t find out already, you can use the planner to reverse-select the color coded pipes to turn them back into the base uncolored versions. Put the planner in your inventory to see the tooltip, it should have instructions :)
