On second thought, the precast in the courtyard and facing Howe are the same colour - I think it is the differnet lighting that makes them look different.

Note the precast with blue inset panel below each western balcony.
Looks like the western side of the south faade will have lighter blue spandrels, so there will be differnetiation between the angled facade and the flanking sections.
Some of the dark blue spandrels on the angled facade seem to be a bit off in colour, esp. when lit from the south.
