Fun fact: The puzzle is still solvable if you replace the bishops rule with:
"Cells 2 diagonal moves from a box's center cell cannot contain that center cell's digit."

That solution does require you to notice the SET/Phistomaphel out the gate and so it doesn't allow for the 6-color jellyfish solution.

You could still solve with whatever method you want if you notice that, for example, purple has to reappear appear in the grid once in each colored verical line and once in each colored vertical line. That means that there are a total of 8 purples in the colored lines/columns, plus the initial appearance, and therefore no more purples anywhere in the grid.
