What colony's founders believed that tolerance was a great virtue?

Pennsylvania is your answer because

William Penn was the colony's founder who believed tolerance was a great virtue. He believed that his colony, although granted by King Charles  II, was a blessing from God. "'Tis a clear and just thing, I believe, to establish such a holy experiment," Penn wrote to one prospective colonist, "for God who has given it to me through many a great trial will bless and make it the seed of a nation." Accordingly, Penn intended to establish an asylum for those who had suffered persecution for their religious convictions, regardless of faith. In this sense, his holy experiment was a religious experience grounded in an unshakable belief in toleration and clearly unique among colonies.
