Origin

According to a famous theory, the idiom has a nautical origin. During the 1600s, the term colors (or colours) refer to the flag or pennant which each ship is legally and morally bound to fly at sea. Soon after that, it also became a common scam of pirates to “sail under false colours” and hoist a friendly flag to get within close range of a targeted ship without alerting them and to hide suspicious activities. And when the pirate ship reached close quarters, would it unfurl its true colors. But the genesis of the idiom is much earlier than the theory above.

The first citation of the phrase is from Thomas Becon’s A Fruitful Treatise of Fasting in 1551, which describes how Satan:

“setteth forth him selfe in his true colours”.

It’s also in Shakespeare, Henry IV Pt 2 (1600) act 2 scene 2:

“How might we see Falstaffe bestow himself to night in his true colours, and not our selues be seene?”

The sense of “colours” meaning livery (or some other show of allegiance), is older than Thomas Becon. But there are also a lot of metaphorical senses for “colour” that may be relevant.

“False colours” began to be recorded in prints from the 1700s.

Synonym

I believe “show true colors” arises from the need of many animals in nature (eg. male hummingbird) to hide its bright colors away from attracting predators. When they are near the opposite gender of the same species (eg. female hummingbird) then they reveal their bright colors (feathers in this instance as a mating display) to show their true colors.
