Sequential flowering as a strategy for maximixing the environmental density of pastel shades

Those are all on the same plant, so they more or less have to be life stages of the same flower.
Well, unless one of them is a highly aberrant parasitic flowering plant, but I rather doubt it, somehow.

probably a centaurea.

I have no reason to believe you're wrong about this plant, though I wonder if a single hydrangea plant could be induced to produce blooms of distinctly differing color (rather than the merely variegated flowers that are common) by, say, mangling the root mass into approximate halves and putting half in acidic soil and the other half in alkaline.

Centaurea? With no little hooves? :)

Whatever it is, there's quite a bit; blue, white, and purple seem to be the predominant colours.

I have no idea what the soil chemistry is like; it almost has to depend on where they hauled it in from, since this is recent post-construction landscaping. But I would not be at all surprised if you could change the flower colours that way.
