A White Surface is better disposed for the Reception of any Colour, than the Surface of any other Body; provided the latter be not transparent. To prove this, we say that every empty Body is capable of receiving that, which another Body, not empty, cannot receive; now if you allow White to be empty, or in other Words void of all Colour, it follows that being illumined by a Body of any Colour whatever, it must retain more of that Colour, than Black, which, like a broken Vessel that has lost its retentive Faculty, lets the Colours slip, as fast as it receives them.
