I agree, designing for 3D printing and more specifically designing for multi-color or multi-material can help save a lot of time and material.
Additionally, printing any number of copies of the same multicolor object will result in the same amount of waste. This doesn't reduce the absolute amount of waste, just makes it a smaller % of the total material used.
Also worth looking into the "wipe into object" setting in the slicer, which will use the color changes in an extra model instead of purging them.
