> I think some of this has to do with practice. Spending a lot of time mixing paint or color correcting photographs is likely to heighten awareness of tiny distinctions. I wouldn't doubt that practice could help, but the test (I believe) was designed to minimize practice effect. I've mixed a lot of color, but one can mix color to a shade only as far as one could determine it's right. It used to be, color matching for printed material was done in large shops by workers visually comparing swatches to customer desired shades. This required training, but not every trainee could master it despite extra effort and time. Seemed it required native ability, talent as it were, to be able to be good at it. Anyway, the online test is solely for one's own interest and information. I don't see there's anything substantial at stake.
