Scene-referred produces washed out final image (vs display-referred)

Red is the dominant color in skin tones this can be confirmed in the waveform but often the vectorscope us used. Many apps have a skin tone line… The scarf is pretty obviously blue. If you set the color picker to restrict to selection it will show you waveforms, parades or points on a vectorscope that represent the selection so its not too hard…you can also always mess with the channels to see where the bright areas are or in the channel mixer show each color channel… a flat tone curve blended in chromaticity or color should also give you a hue map of the image…
