Morphology

Prussian + blue

The phrase combines 'Prussian' (of or associated with Prussia) with 'blue', so a learner who knows both words would naturally infer it names a kind of blue associated with Prussia. While the precise hue or pigment history (deep, slightly greenish) may require exposure, the basic sense 'a type of blue color' is transparently derivable from the constituents.

Etymology

The color Prussian blue may come from early 1700s Prussia, a German area long ago, where a maker accidentally mixed iron with another chemical and made a very deep blue. That's why the name Prussian blue now means a deep, greenish 'blue' color used in paint and art.
