Star - Temperature, Spectral Types, Luminosity: Stars differ in colour. Most of the stars in the constellation Orion visible to the naked eye are blue-white, most notably Rigel (Beta Orionis), but Betelgeuse (Alpha Orionis) is a deep red. In the telescope, Albireo (Beta Cygni) is seen as two stars, one blue and the other orange. One quantitative means of measuring stellar colours involves a.
The hotter a star is, the more it shifts to the higher end of the color spectrum. That's why blue-colored stars are actually the hottest, with a temperature range of 30,000 to 50,000 Kelvin. As a star cools, it shifts to the lower end of the color spectrum, with a red star ranging between 2,000 and 3,500 Kelvin.
Color and Temperature As we learned in The Electromagnetic Spectrum section, Wien's law relates stellar color to stellar temperature. Blue colors dominate the visible light output of very hot stars (with much additional radiation in the ultraviolet).
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.

Figure 17.3 Sagittarius Star Cloud. This image, which was taken by the Hubble Space Telescope, shows stars in the direction toward the center of the Milky Way Galaxy. The bright stars glitter like colored jewels on a black velvet background. The color of a star indicates its temperature. Blue-white stars are much hotter than the Sun, whereas red stars are cooler. On average, the stars in this.

The colors of stars from hottest to coldest are blue, blue-white, yellow, orange, and red. The colors of the stars indicate their surface temperatures. There are five star colors: blue, white, yellow, orange, and red.
The hotter a star is, the more it shifts to the higher end of the color spectrum. That's why blue-colored stars are actually the hottest, with a temperature range of 30,000 to 50,000 Kelvin. As a star cools, it shifts to the lower end of the color spectrum, with a red star ranging between 2,000 and 3,500 Kelvin.
Look at the beautiful picture of the stars in the Sagittarius Star Cloud shown in Figure 17.3. The stars show a multitude of colors, including red, orange, yellow, white, and blue. As we have seen, stars are not all the same color because they do not all have identical temperatures. To define color precisely, astronomers have devised quantitative methods for characterizing the color of a star.

One summary comment about this discussion is that stars can be roughly classified by their colors, since the spectral types are arranged by temperature. Also, the apparent color of a star gives you a measurement of its temperature, but more accurate classification usually requires a high quality spectrum.

Star Colors: Why They Differ And What We Can Learn From Them | Color ...
The colors of stars from hottest to coldest are blue, blue-white, yellow, orange, and red. The colors of the stars indicate their surface temperatures. There are five star colors: blue, white, yellow, orange, and red.
Blue stars are the hottest, with surface temperatures exceeding 30,000 Kelvin (K). As the temperature decreases, the color moves through blue-white, white, and yellow-white. Our Sun is a yellow star with a surface temperature of about 5,780 K, placing it in the middle of the spectrum.
