Morphology
light + the + blue + touchpaper
The meaning is partly derivable from the literal image: 'light' (set on fire) + 'touchpaper' (paper used to ignite fireworks) yields the metaphor of triggering a rapid, explosive chain reaction, so the core idea of 'cause something to start quickly' can be inferred. However, 'touchpaper' is a culture-specific, somewhat technical term and the adjective 'blue' is largely stylistic, so the precise idiomatic nuance is not fully predictable for a B1 learner without prior exposure.
Etymology
The expression light the blue touchpaper comes from fireworks. You light a long blue strip called the blue touchpaper, and when it burns down it makes the firework go off quickly, so the phrase now means 'to start something that will quickly become exciting or cause a strong reaction'.
