You need the secondary colours, i.e. cyan, magenta and yellow when mixing pigments that absorb and reflect light as they are subtractive. The primary colours are used for processes where the colours add.
you would also need black and white filaments for color mixing to create the proper shade.
Yes you will certainly need white as well because in 2D printing you get white by not printing anything and letting the paper show but that doesn't work in 3D. In theory cyan + magenta + yellow makes black. In practice black is used as well to save ink and get a more accurate black.

How does it achieve good mixing where Bath university and RichRap failed?

Yes you can build your own colour scheme. I used the basic red, yellow and blue(Not RGQuote
Ohmarinus
So, if you manage to mix two colors, do you get a new color if you are using three primary colors as base filament? That way it theoretically *should* be possible to output RGB values.
In the image below I started off with red then added 10% yellow and decreased the red with 10% in stages until pure yellow then did the same with blue until pure blue and then again with red until pure red.
Then printed pure yellow,red,yellow,blue, yellow and then added red and blue to the yellow in the same percentage (printing all three colours at the same time at different percentages) to the top.

Hi Xabbax, I really would like to recreate this effect with my prusa i3 printer. I cannot find any code example that shows how to use the M163 and M164 color mixing code. Can you share some gcode tips on the color mixing?
I am currently using v92 firmware and I only need to figure out how to generate the correct gcode... thx ahead
