You could try setting a custom WB (where you shoot a gray or white card that fills most of the frame, then choose that in the image after selecting Custom WB from one of the shooting menus), and set your WB to Custom. Instead of a gray card, you can also use one of the WB filters that hash the incoming light to 18% gray (ExpoDisc, ColorRight, etc.).


Depending on how accurate you want it to be, you may need to redo the custom WB for different settings (for example, rooms in my house have different proportions of tungsten and fluorescent lighting, and before the sun goes down there are varying amounts of daylight entering from outside, which may or may not be filtered by clouds or sheer curtains).
