I don't think anyone could pick up on it with the naked eye at all. While I cannot recall exactly what the numbers ended up being (Harp would probably remember better than I would), it was a drop of 3 or 4 points in one of the RGB numbers I think.In one year...when the color shifts, is it too obvious for some one without a colorimeter ? I asked Harp if I can repaint with the Henry mix again, and he said maybe...
