Iriseren

Iriseren på en sæbeboble.

Iriseren (også kaldet irisering, (perlemorsagtigt) farvespil, regnbueglans og perlemorsglans) er en farve, som skifter farve alt afhængig af, hvilken vinkel den ses fra. Iriseren forekommer naturligt, men kan også skabes kunstigt. Iriseren ses flere eksempelvis på sæbebobler, CD'er og spildt benzin. Kan også ses på fjer, muslinger, insekter, maling, slanger, fisk, sten, skyer og planter (sjældent). Iris kommer af det græske ord ἶρις (îris), som betyder regnbue.
