This is a classic put yourself in their shoes logic riddle. Even without vocal (which is the more common of the approaches: #3 says I'm not sure, #2 says the same; #1 could even be blind as what they can see wouldn't matter to the riddle) the implied logic from chair #1 is that neither #2 nor #3 can accurately gauge their correct color. For this to happen, with 3x blue and 2x white, we know what #3 can only see that #2 and #1 wear either:#2 blue, #1 blue #2 white, #1 blue #2 blue, #1 white #3 can only determine their colour if both #2 and #1 were wearing white. Therefore we know that both #2 and #1 are not wearing white. Using the same implied logic, since #2 also cannot determine their colour, and #2 knows that #3 can only see one of the possible combinations above, the only possible colour that #1 can be wearing so #2 can accurately determine their colour is option number 3. Since #2 also cannot determine their colour, this therefore results in #1 wearing blue. This is one of my favorite riddles as it is difficult to determine until you put yourself in their shoes one at a time.
