Thank you very mnuch for the info.
Wow, i had never thought that those shots had indeed a sky blue backgound.
i was so used to the dark-almost black background and it also made sense narratively…
Anytime! I’m happy to help anyway that I can. ^-^
I swear I’m NOT trying to turn this into a Beauty and the Beast color discussion, but I can certainly empathize with finding a color choice (or discrepancy) making more sense in the body of the narrative. Remember how in the VHS version of BatB the Beast was almost silhouetted in both the prologue and his introduction scene in the castle den? I LOVED that. It made it far more menacing to leave the details of his body mostly to the imagination, save for his white teeth and the sclera of his eyes.
Likewise, that darkened background in that Toccata shot certainly gave the abstract imagery more focus. =D
EDIT: I… think my TV from way back wasn’t properly calibrated or something, 'cause I just went back to both of those scenes and the Beast is very clearly seen. Disregard everything I just said. xD
