White stars are hotter than red and yellow. Blue stars are the hottest stars of all.
KEY CONCEPTS AND SUMMARY
Stars have different colors, which are indicators of temperature. The hottest stars tend to appear blue or blue-white, whereas the coolest stars are red. A color index of a star is the difference in the magnitudes measured at any two wavelengths and is one way that astronomers measure and express the temperature of stars.

What color are the hottest stars in the universe?
Blue stars are the hottest stars on the spectrum, and they’re also massive. Rigel is a blue star in the constellation Orion, and it’s about 17 times the mass of the Sun and 40,000 times as bright. The hottest blue stars in the known universe are more than 100 times the mass of the Sun. Step 2 : Answer to the question “What color are the Visit site
The hottest stars are the blue stars. A star appears blue once its surface temperature gets above 10,000 Kelvin, or so, a star will appear blue to our eyes. So the hottest stars in the Universe are going to be a blue star, and we know they’re going to be massive.
Why are the hottest stars blue in color?
The colour that we see is usually an additive combination of the emissions from each wavelength. Hot stars appear blue because most energy is emitted in the bluer parts of the spectrum. There is little emission in the blue parts of the spectrum for cool stars – they appear red.
