Have you experienced a measured colorimetric accuracy of two samples that failed to be visually accurate?
YES! OH YES! With regular cinema projectors, observer metamerism is so great that on occasion a group of golden eyes could not agree on whether a color matches or not. Luckily that has nothing to do with whether the colors are pleasing. Next check out laser projectors! Have you measured your eyes lately? Which category of standard observer are you in NOW?

Just after finishing this message, in my inbox arrives a paper titled "COLOURIMETRIC OBSERVER CATEGORIES AND THEIR APPLICATIONS IN COLOUR AND VISION SCIENCES" by Sarkar, A., Blondé, L. What a coincidence!
