    Luminance Formulae and Red Distortion


      I'm working on a chart that displays and names a couple hundred color swatches.  I have all of their color data in a table, and I want to arrange them by hue and lightness, so I applied the Rec.709 coefficients to my data.  This arranges my colors into a natural gradient--except for the reds, which have some glaring missplacement.  Any idea why .709 coefficients do this, or what coefficients I should use instead?
