Two-color exchangeability does not imply exchangeability

We provide simple examples of two-color exchangeable sequences \(\xi=(\xi_1, \xi_2, \ldots, \xi_n)\) that are not exchangeable. This answers a question of Bladt and Shaiderman~\cite[Question 2.6]{bladt2019characterisation} for finite two-color exchangeable sequences.
