Red is the least hot.
Red stars are the coolest and least hot type of stars. They have surface temperatures around 2,500 to 3,500 degrees Kelvin.
how cold or hot it is
Yes, very hot stars emit more blue light due to their high temperature. This blue-white color is a characteristic of stars with surface temperatures upwards of 10,000 Kelvin.
Hot stars are typically blue or white in color. These stars have higher surface temperatures, often exceeding 10,000 degrees Celsius (18,000 degrees Fahrenheit). Their intense heat results in the emission of light at shorter wavelengths, which gives them their blue or white appearance. Examples of hot stars include O-type and B-type stars in the stellar classification system.
It depends on the stars wave-lengths for most of it. Stars that are cool (for stars at least- measured in kelvin) normally radiate there energy in the electromagnetic spectrum as red. Even though all stars in the sky appear to be white. Hot stars radiate much larger wave lengths, causing an almost blue color to be emitted. The only way for us to know how hot a star is... is finding where it's wavelengths are at there "peek". Wave lengths are NOT visible to the human eye.

All stars are hot. Their temperature can be determined by their color. The "coolest" stars are red in color. As temperature increases stars will go through orange, yellow, white, and finally blue for the hottest stars.
The color of the stars depend on how hot they burn.
how cold or hot it is
the color of the stars usually determines how old and how hot the star is it can also determine when the star will go supernova
Yes, very hot stars emit more blue light due to their high temperature. This blue-white color is a characteristic of stars with surface temperatures upwards of 10,000 Kelvin.
they can range from red for the least hot stars, through orange, yellow and eventually to white and blue for the hottest stars.
blue stars are the hottest, although red, orange and yellow stars are pretty hot too.

The color of any start is a direct result of the stars internal temperature. The hottest stars are bluish-white, very hot stars are white, the yellow stars, like out sun, not quite as hot, and finally red stars, which while still very hot, are the coolest of the stellar types. It is analogous to heating a steel bar in a forge, First it will get red hot, then yellow, and so on until it reaches white or bluish-white in heat.
Yes, stars can be as hot as the sun and even hotter. The temperature of stars varies depending on their size, age, and stage of evolution. The sun is a relatively small, average-temperature star compared to others in the universe.
It depends on the color - like how stars work so it would be very very hot!
