And the point isn't that camera filters don't overlap, it's that the sensitivity peaks are spread evenly across the spectrum and the overlap is more or less even. ("Monochromatic" narrow-band photosites, even if they existed, would've been useless for photography as they wouldn't register in-between wavelengths at all - e.g. a photo of a rainbow would show three thin lines)
