Minting InstructionsMixer/Splitter: Allow primary color to mix into composite colors (composite colors need to be checked too).
Composite Colors: Will allow composite colors to exist; can work without mixers; they will be on their own circuits.
Off-center pipes: Pipes don't have to be centered on their tiles.
Grayscale: Will apply a grayscale filter to all the colors. Why would you do that?
Color Mode: Pick your primary colors.
Pipe Material: Color for metal pipes.
