@wmvanvliet EvokedField._on_colormap_range has a comparison if type == "meg", but type here is the builtin type rather than something passed by kwarg for example:

When you get a chance can you fix this?

Bonus points for removing these shadowing of builtins, it's a reason we generally prefer stuff like type_ to type when not use the builtin -- the flake / ruff check would have caught this issue then!
