How does Tom Wolfe use imagery in From Bauhaus to Our House?

Imagery:

“They became desperate for an antidote, such as coziness & color. They tried to bury the obligatory white sofas under Thai-silk throw pillows of every rebellious, iridescent shade of Magenta, pink, and tropical green imaginable. But the architect returned, as he always does, like the conscience of a Calvinist, and he lectured them and hectored them and chucked the shimmering little sweet things out.”
