I don't think so Metatron. In fact David is closer to seeing the "truer" colour. I also see a "greyness" to that strawberry picture, but more so on the background. But supposedly that picture is supposedly free of red pixels.

While all this is interesting it is not what the thread was originally about. ie the illusory nature of colour in general.
