The noun candor is a quality of being completely open, unreserved, sincere and honest.

Synonyms are bluntness, candidness, plainness, or truthfulness.

The word origins from Latin (c. 1600) candor meaning “purity, openness”, originally “whiteness, brightness, radiance” and from candere meaning “to shine, to be white”. It was also borrowed earlier in English (c. 1500) with the Latin literal sense “extreme whiteness”.
