Colours confused with neutrals (Hex)

This table holds a subset of the standard 216 colour web palette where the hues as seen by protanopes and deuteranopes tend to be confused with neutrals.* [Note that it is not corrected for the loss of luminence experienced by protanopes at the longer wavelengths.]

The point at which the perceived colours cross from blue to yellow varies slightly in the two palettes, and hence many be neutral for one palette, while being clearly tending towards blue or yellow for the other palette.
