The print preview of sliced objects does not support the "set (and save) mix factor" G-Codes, M163 and M164. To be fair, the entire Cura interface does not support mixing in general. References: https://reprap.org/wiki/G-code#M163:_Set_weight_of_mixed_material http://marlinfw.org/docs/gcode/M163.html Printers with mixing extruders/heads can produce an array of colors from two or more filaments, but this is not rendered as expected in the Print Preview of Cura (nor in your competitors like Repetier-Host, etc.). This makes it hard to confirm that the applied color mixing is as expected before printing.
