Common Pitfalls

  • Do not translate literally as 'ложные краски' (incorrect). The concept is 'притворство', 'обман', 'лицемерие'. The idiom 'под чужим флагом' is a close equivalent for 'sail under false colours'.

Common Mistakes

  • Using singular 'colour/color' (e.g., 'false color'). The phrase is almost always plural. Confusing 'false colours' with 'true colours'—they are antonyms in context.
