Epson 1810 with an average error of 2 DE LabABOVE:
The report data translated into a Lab plot with arrows showing the change of colour away from the target point. In prints desaturation is often present but the projector expands the gamut in the yellows and yellow greens. The skin errors, compromised by the poor reds, are some of the larger overall errors.
The hue and chroma (saturation) portions of the errors are plotted on a polar diagram. The further a point is from the origin (the 0, 0 point) the worse the error. The coloured dots are an indication of the position of the error point on the colour wheel. Visually hue errors are the most costly in terms of damaging the look of a projected image. The skin tones are poor performers.
