What does discolored mean?
"Discolored" describes something whose original color has changed — usually unevenly, through fading, staining, yellowing, or tarnishing. It is most often used as an adjective, whether describing household objects (a discolored ceiling, discolored curtains), natural materials (old paper, aged ivory), or parts of the body such as teeth, skin, or nails, where it can signal damage, decay, or illness. The word carries a mildly negative tone, implying deterioration rather than deliberate change, and appears frequently in practical contexts like home inspection, dentistry, medicine, and art restoration. It derives from the verb "discolor," formed from the prefix "dis-" (indicating reversal or removal) combined with "color," ultimately rooted in the Latin "color." Its close noun form is "discoloration," which names the change itself rather than the affected object. Because it is precise yet broadly applicable, "discolored" is a useful alternative to vaguer words like "dirty" or "old" when the specific issue is a shift in color.
Changed from its original color; faded, stained, or marked with abnormal patches of hue.

Past tense and past participle of "discolor": to lose, or cause to lose, its original color.

In American English the verb is usually spelled "discolor"; in British English, "discolour."
That yellow tinge on an old book page isn't dirt — it's the paper literally oxidizing, which is why 'discolored' often signals age rather than neglect.
