The colour of a star tells us a lot about its temperature, age, and even its life stage. The Science Behind Star Colours The colour of a star depends primarily on its surface temperature. Cooler stars emit more red light, while hotter stars give off more blue or violet light.
Blue colours dominate the visible light output of very hot stars (with much additional radiation in the ultraviolet). On the other hand, cool stars emit most of their visible light energy at red wavelengths (with more radiation coming off in the infrared) Figure 2 shows star colours and their corresponding temperature.
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.
The hottest stars have temperatures of over 40,000 K, and the coolest stars have temperatures of about 2000 K. Our Sun's surface temperature is about 6000 K; its peak wavelength color is a slightly greenish.

Star colours are an indication of how hot a star's visible 'surface' is. As a star's temperature increases, as a result of there being more gas in the star - and hence more fuel to burn - it becomes hotter. Its colour changes from orange, through yellow, to white. Hottest stars are blue, with temperatures up to 40,000ºC.
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.

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 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.
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.
