How to do 4 Colors, 1 Layer, Dual Head XL
I apologize if this has been addressed, did alot of searching and did not find a clear answer. Is it possible to print multiple colors in a single layer with dual head XL. In my case I was trying to do 4 colors. I've broken the model into parts and selected multiple extruders, assigned colors but get unassigned gcode filament errors when I try to print. I'm okay with swapping colors with a single head if needed, would prefer using both heads. I find bits and pieces on how to do it with MK4 but nothing clear for XL dual head.
RE:
Yes, you can, and in fact in a way it's a key selling point of a tool changer. What you've described is the right approach, why you're getting errors is impossible to know without seeing your model. Can you save it as a 3mf project file, then zip compress it and upload it here. Zip compress is important because the forum software has not been configured to accept 3mf files. To upload the .zip file, use the Attach file option that's available beneath the text edit box. Add Media should also work.

So I've tried copying the method used for the MK4, changed extruders to 4 (4 colors) and selected single extruder multi material. When I go to print I get this error on the printer, not sure how to proceed. Attached is my project, ideally I would have 2 colors for each head, not sure how to do this.

Oops, I missed the small—but critical—fact that you're trying to do this on a 2 toolhead machine ☹️
I don't know it that's even possible. On a single extruder printer you can "fake" a multi extruder setup because when the printer sees a tool change, the firmware makes it just unload the filament and offer to load the new. On a multi-extruder machine, I guess it thinks those extruders actually exist and thus tries to use them instead. I guess one could go into the gcode and replace all mentions of T3 or T4 with T1 or T2 but you'd also have to somehow add the code for unload/loading filament, and frankly, I'd be scared to screw something up doing all that.
Maybe someone else has ideas?

I tried fooling the printer by using the single extruder XL preset, same errors. I've successfully used different materials and colors using the two heads but never tried more than 2 colors in one layer or see a way to do so in the slicer.
