Several of the tiny frogs among the dendrobatids display some tinges of blue.
Question: What is the blue dart frog that is not Dendrobates azureus? It’s normally green and black but is sometimes available in blue and black. I think it’s a color phase of a common species.

Answer: Several of the tiny frogs among the dendrobatids display some tinges of blue, including variations of Dendrobates tinctorius, but the only other species that leaps to my mind with the description you provided is the blue phase of D. auratus, which occurs in the wild from southern Nicaragua to northwestern Colombia. Several localities in Panama are home to blue and black specimens, and blue morphs show up in other populations, too.
