True colours refers to a person’s real character, motives, loyalties, or feelings as revealed beneath outward appearance. In poetry, the idiom has visual and heraldic force, suggesting banners, dyes, masks, and display. It often appears when deception fails, courage appears, or hypocrisy is exposed. A poet may use it in love, politics, betrayal, or moral testing. The phrase is useful for exploring revelation, authenticity, and the dramatic moment when concealed identity becomes visible.

True colours means real character, motives, or allegiance, especially when revealed after concealment.
