Anyway, I was getting a Greco-Roman vibe, so I figured it could be Hecate, since she is an incredibly popular goddess on both sides of the fence(meaning both RHP and LHP). Although, Hecate is a cross-pantheonal triple goddess, so there is way more complexity to her than being one of the most powerful and balanced goddesses of the Greek pantheon.
But yes, blue does make sense. If you couldn't pick up on any words, then that may be Athena's way of communicating to let you know she is there. Next time, have a pen and paper ready.
While in a trance, ''drop mind'' so to speak, in that you will try to quiet your own mind. Ask Athena the question out loud and write down the first thoughts that come into your mind. The sentences there. I would advise you learn to meditate, or perform other exercises for your focus so that you do not get distracted.
Once you have finished this, move onto the next question. Repeat this process, do not doubt yourself, write the first answer down, and check back after maybe twelve questions. You will see clearly that the answers aren't something your mind could've fabricated, simply because the diction, syntax, vocabulary, contents, or even just the FEELING of the words is definitely not yours.
So...congrats! Good luck with the silver-eyed goddess.
