Iriseren
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.

This image depicts a flat view of a CD-R with interference colours. It was scanned with an HP ScanJet 4400c, and ran through ACDSee's auto-level filter. One fallback of the image are the dust fibres. It was initially saved as .JPG with IrfanView at 90% quality, and then converted to .PNG to add transparency.
