Actually, it's more likely to be invisible than a single colour if there are a lot of higher frequencies in the image (something that will be rare until we have patterns). Clearly it would be hard to see on a background of black and white angular regions.
Not that I know a better solution, perhaps pick one of three colours that is maximally distant from the underlying colours.
Well, I suppose we could apply a low-pass filter when selecting the inverse colors?
