they are indeed not well used characters by JRRT, but i think they wont be blue wizards. because in the end both turned to evil. even after Sauron's fall JRRT implied they're still out there manipulating kingdoms of men to turn to evil.

That was the initial idea, however Tolkien, as he did on several occasions, changed his mind on this later on & gave them a happy ending
Initially it was Alatar & Pallando came to middle-earth in the 3rd age with the other 3 wizards to stop Sauron, however they eventually failed their task, & were probably corrupted similar to Saruman, & may have founded magic cults in the east & south.
Later on Tolkien said, ya know what, actually I think they came to middle-earth in the second age, went to the east & South, & were successful enough to when those forces joined Sauron, they didn’t outnumber the forces of the west.
