Colista is a female name that could be a variant spelling of Calista, the feminine form of Callistus, the Latin form of Greek Kallisto meaning “most beautiful” from kalos (beautiful). It could also be a combination of Colette (the short form of Nicolette, feminine form of Greek Nicholas meaning “victory of the people”) and Calista.
Colista is also a Spanish word, apparently referring to the bottom or last of something or someone (like the bottom team of a soccer league). It also has some use as a surname although there wasn’t much I could find behind it’s meaning and origin.
Origin: Ancient Greek, Spanish
