the star is so bright so thats why we can see it
The colder a star is the longer the light waves it emits. Light wavelength is what we perceive as color.
Orange - if 5,000 Kelvin
because since its very hot the hotter it gets it starts to melt the color on the star.For Example blue stars. there the hottest star.
Actually, it is more the other way around. A lower-temperature older star like Sol (our sun) is probably classed as a somewhat yellow star.A new, big star is going to be more on the faintly blue side...
