It would be great if it was possible to fill a bucket with ink in the color picker, and then dump it to get liquid ink on the ground for decorational purposes.

Perhaps the ink could even apply a minor buff while standing in it; like pink applying a very weak regeneration or magenta making your buffs expire slightly faster.

Mostly i just want to have fun colored water flowing in my base.

Since Ink behaves more like a gas, I do not think adding a fluid variant would be fitting, thematically. Some other form of colored fluid could be nice, though.

That would indeed be cool and would nicely fit into the theme of the next update. Maybe, maybe!
