The concept of "Full Spectrum" color blending has just dropped on the toolchanger community over the last month. See this Reddit thread for more information. It uses the concept of dithering to create new colors by alternating (or creating patterns of) layers in different colors. Think the old Ziploc bag "Yellow and Blue make Green" commercial.
You can download the Full Spectrum fork of Snapmaker's fork of Orca Slicer to get started and it works natively with the Prusa XL. The process is pretty easy and it "just works" out of the box. However, there are a few things you need to understand about color mixing. The colors don't mix perfectly with filament opacity and other factors meaning that your color output will be dependent on the specific characteristics of the filament you're using.
I"ve uploaded my chicken printed with PolyMaker PolyChroma PLA, which is a nice translucent PLA that works well for these situations. My red is a lot oranger than I'd like but I'd need a translucent black to darken the magenta and... well... I forgot to buy that.
My chicken results closely matches the results Wombley got in his video on the topic.
Basically, all this boils down to the only way to know what color you're going to get is to print it. As a result, I made this test palette to give mixes for all combinations of all five extruders on the 5 toolhead XL. Each row is a tool combination and each column is the most likely viable mixes for that row (100%:0%, 66%:33%, 50%:50%, 33%:66%, 0%:100%).
I created the small version (5mm pegs, 2.5 hours, 0.1mm layers) first but found that the pegs were too small for reliably good print quality so I made a larger version (10mm pegs, 5 hours, 0.1mm layers). Ultimately, I settled on the 7.5mm version as a nice compromise. The F3D file is parametric and currently set at 10mm.
By default the Full Spectrum fork creates 50:50 combinations for all toolheads but it's up to you to create the 66:33 and 33:66 versions. The 3MF files attached have the colors appropriately created and mapped. All you have to do is select your materials and you should be good to go.
