Abstract
Let \(\overline{p}_{-t}(n)\) count the number of t-colored overpartition of n, with t= 5, 7, 11 and 13. We find several infinite families of congruences modulo 16 and 32 for \(\overline{p}_{-t}(n)\). For example, For each \(\alpha\), \(\beta\) and \(\gamma \ge 0\),
where \(t_5\in \{7, 23, 31, 39\}.\)
