Using a set of red samples, we investigated the influence of the number of observers and samples on the accuracy of experimentally evaluated color‐difference ellipsoids. The results show that an ellipsoid can be calculated with an accuracy corresponding to a mean error of calculated color differences below 10% if a set of about 50 samples is assessed 30 times by pair comparison, e.g., 15 observers twice each.
