- Do not confuse with 'iridocyclitis' (medical term). The Russian verb 'радужить' is poetic and not a direct equivalent. The closest technical term might be 'наносить радужное покрытие'.
Common Mistakes
- Confusing it with 'iodize' (to treat with iodine).
- Using it as a synonym for 'decorate' generally (it's specific to an optical effect).
- Misspelling as 'iridise' (US 'z' is standard even in technical English).
