Getting the same values to have the same colors across multiple plots of spatial_segment?

Help squidpy

I’m calling:

    sq.pl.spatial_segment(
        fov,
        color=['method_1', 'method_2'],
        library_key="fov",
        library_id=fov_num,
        seg_cell_id="cell_ID",
        title=f"{method}, FOV {fov_num} (N={fov.n_obs} cells)",
        )

I want to set a pallet that assigns a constant colour to each category such that both sublots will be consistent, and when plotting across different FOVs as well.
The pallet argument only accepts a flat list, not a dict, so I have no idea how to do this.
Thanks!
