Will platinum rings change color?
No...one of the characteristics of a platinum metal ( there are 6 of them) is that it will not tarnish or oxidize in any way. If your platinum is tarnishing then it is probably: A) another metal such as silver with a platinum or rhodium plating or B) a cheap alloy of palladium and and another metal which will oxidize. That's not completely true: any metal can develop a patina, which can slightly change the color. However it does not turn yellow, green, or brown but slightly grayer (duller) which many people perceive as "whiter" though it is less shiny. Updated: Compared to white gold (it's usual alternate) it doesn't change color. White gold has a yellowish tint to start off and eventually turns more yellow over time as it's finish wears off. Platinum remains its original silver tone.
