In this work, we present an online test designed to ascertain what type of misconceptions people may have about color perception. It is noteworthy that only 15.7% of the over 20,000 respondents answered correctly, and that the vast majority (78.2%) of incorrect response patterns on our test matched to just four sequences, corresponding with four types of misconceptions.
