Is our accepted color space wrong?

The way we use 3 primaries is a basically a trick, though one that works very well in most cases. For example there's the essentially monochrormatic yellow/orange light from a sodium lamp. Or you can mix RGB primaries to match it. But many objects illuminated by one will look different when illuminated by the other. This is an extreme illustration of metamerism.

In your bathroom your white ceramic basin and resin bath may look the same in daylight but different in electric light. And different people may see the effect differently.

All our colour reproduction processes, whether additive (RGB on screens) or subtractive (CYMK in print) are fooling the eye to a greater or lesser extent. But it all works amazingly well most of the time.
