Morphology

blackjack = black + jack (semi-transparent) = black + jack

Structurally 'black' + 'jack' (with 'jack' meaning a small flag) fits the sense, but 'jack' in the sense 'flag' is less familiar to average learners.

Etymology

The word blackjack for a pirate flag comes from black for the color and jack meaning a small ship's flag, so it is a black flag flown to warn and frighten other ships.
