 The relativizing approach says that if a simple, o, is white in one region and grey in another, then o bears the being white at relation to the first region and the being grey at relation to the second; it need not have a part that instantiates the property whiteness or a part that instantiates the property greyness. Alternatively, one might treat instantiation as a three-place relation, and say that o instantiates the property whiteness at one region and instantiates the property greyness at another.
