We often mistake the light for the object.

An object which absorbs all blue light but reflecting all red and one-quarter of green light will produce the sensation an object say is orange.

But let us make it clear—the light is always the same combination of reflected red and green light with the absorption of blue light by an object that makes the object appear to be orange. Nothing materially orange can be found in the orange, and nothing materially orange can be removed from the the object to be its own object “orange”.

All the way down all we find is light or energy.
