Do Biotics turn blue when...

They have a blue aura around them when they use their biotics (that can be seen throughout all three games). They can also make the same aura appear when their biotics are powering up for potential use, as demonstrated by Liara on Noveria when Maeko Matsuo suggests securing Shepard's weapon. Non-blue biotics (i.e. non-Asari), however, don't turn blue when having sex, as shown in Miranda's romance scene with Shepard in ME2. Jack does exhibit a blue aura during the catfight with Miranda in ME2, but she's also using her biotics to throw furniture around at that moment, so I don't think it's because she's angry, but rather it's because she's using her biotics.

I don't know what any of the books or comics might imply differently. This is just my conclusion based on what we're shown within the games.

I think theres a brief scene wher Corahas a blue aura when she's kicking a box in MEA in one of you rfirst conversations with he raboard the Tempest. But again I think it's just her using he rbiotics out o ffrustration much like he Jack Miranda fight you mentioned or even when Liara confronts Javik after Thessia.
