The colder a star is the longer the light waves it emits. Light wavelength is what we perceive as color.
you can tell the temperature by its color
A star's color is determined by its surface temperature. This temperature is largely dependent on the star's initial mass.
by it's color
The color depends on the star's temperature. For example, a blue star is hotter than a red star.
The Color of stars depends upon their surface temperature.
Star colors tell us how hot the star is. For example a red colored star is cool and a blue colored star is hot.
The color of a star is a clue to its temperature. Hotter stars tend to be blue or white, while cooler stars appear red. This is because the wavelength of light emitted by a star changes with temperature, leading to different colors.
Different colors of stars "usually" means different temperatures. I don't remember the temperature that each color corresponds with, but when stars are different colors it is usually due to their temperature.
The second hottest star would typically appear blue in color. Stars emit different colors based on their temperature, with blue indicating a very high temperature.
The five possible colors of a star are blue, white, yellow, orange, and red. These colors correspond to different temperature ranges of stars, with blue being the hottest and red being the coolest.
Brightness tells you the temperature and mostly temperature would tell the brightness of the star that we are talking about.
actually, it depends on the color of it's chromosphere. as you get deeper into a star, it may change color due to it's temperature, but what you see on the outside would be a different color. The chromosphere would hide the inner core of the star.
