NTSC colors were bad - really bad - but wideband bayer filters + sRGB are the source of the mediocre colors we see today. We could have beautiful Kodachrome quality colors If we used narrow-band RGB filters and a wide gamut (Rec.2020, or Rec.2100PQ) colorspace. If you look at the spectral sensitivity specs of Kodachrome film they are fairly narrow-band and closely matched the perceptual sensitivity of human vision (CIE 1931). If you display an sRGB encoded image with Rec.2020 gamut (without colorspace conversion) the colors will appear very washed out. If you display a Rec.2020 encoded image on sRGB (without colorspace conversion) it will appear oversaturated. Separately, narrower and/or more widely spaced bandpass filters will increase color saturation. It turns out that narrow-band filters approximating the CIE1931 curves are a natural match for the Rec.2020 colorspace. Since CIE1931 approximates how humans perceive color the colors are also more accurate. It was a "lucky" accident that the properties of CRT phosphors, from which sRGB is derived were a good match for the wideband color filters used in color video cameras.
