It's not. White is the hottest. Then blue, yellow orange, red.
The blue star is the hottest.
Yes it is
yes
If a blue star wasn't so hot - it wouldn't be a blue star - it would be a white star.See related question for more details.
blue stars are hotter
False. Blue giants(or hypergiants) are hotter than Red giant stars. White dwarves are also hotter but they are smaller than blue giants. (As is implied by the name.)
No. Color, for stars, is (almost) entirely dependent on "surface" temperature, and white stars are significantly hotter then red ones. (The order from coolest to hottest goes brown, red, orange, yellow, yellow-white, white, blue-white, blue).
Sun
The color of a star is influenced by its temperature, with blue stars being hotter than red stars. Therefore, you could conclude that the blue star is hotter than the red star. Additionally, blue stars typically have shorter lifespans than red stars.
Blue or purple stars are hotter than the whites
A white star is hotter than a yellow star primarily due to its surface temperature. The color of a star indicates its temperature, with blue and white stars being hotter than yellow, orange, or red stars. White stars typically have surface temperatures ranging from about 7,500 to 10,000 Kelvin, while yellow stars, like our Sun, have temperatures around 5,500 to 6,000 Kelvin. This difference in temperature is a result of the star's mass, age, and stage in the stellar lifecycle.
Well I know this is not what you had in mind but white stars are hotter! If you where to compare, the blue stars would be hottest then the white stars, yellowish white, yellow orange then red. I know many people would have thought diffrently so face it our star (the sun) isn't the hottest.
