IPA: //mɪsˈkʌləd//
KK: /mɪsˈkʌlɚd/
Having an incorrect or unnatural color; not colored as expected or intended.
The painting looked strange because it was miscolored in several areas.
Miscolored → It is formed from "mis-" (meaning wrongly or badly) and "colored" (from the root "color" which comes from Latin "color", meaning hue or appearance). The word "miscolored" means having the wrong or bad color, or being improperly colored.
Think of 'mis-' meaning wrongly, and 'colored' referring to hue — so miscolored means having the wrong hue.
