Morphology

show + one + true + color

While 'show' and 'true' transparently signal 'reveal something genuine', the noun 'colors' is metaphorical for character or intentions and is not a literal meaning learners will reliably map from the word 'color'. Because part of the meaning is compositional but the key metaphorical link ('colors' = character) is conventional and not obvious without exposure, this expression is best judged semi-transparent.

Etymology

Show one's true colors may come from old sailors and ships. Captains would sometimes sail under a fake flag to get close, then raise their real colors ('flags') before a fight, so the phrase now means 'to reveal your real character or intentions'.
