- 39,700 KThe temperature of a purple star depends on the classification system used. According to the black-body spectrum, violet occurs at a temperature around 39,700 K, which is hotter than a blue star (~25000 K)1. Violet stars are of two temperature ranges: those whose Planckian peak wavelength lies between 380 and 450 nm, or 6700-7900 K temperature and those above the violet range in the ultraviolet that appear violet to blue in color2. Hot stars emit more blue and violet light than red and orange light3.Learn more:✕This summary was generated using AI based on multiple online sources.
