PROBLEM: This is the science of spectroanalysis and the scientists can detect not only the star's color, but what the star is actually made up of. The elements of a star will help as we classify the solar systems and galaxies that we discover. Useful Websites. Star Colors and Temperatures. Why are the stars different colors? Color is a result of the way gemstones absorb light. Light is an electromagnetic vibration at certain wavelengths. The human eye can only perceive wavelengths between 380 and 750 nm. The colors of the spectrum that are visible to us are red, orange, yellow, green, blue and violet. If all the different wavelengths of light pass through a gemstone, it will appear colorless. On the other hand, if the gem material absorbs all light, it will be appear black. There is another important factor that can alter a stars color. If the star has any elements in its atmosphere it can change the light wavelength and that will cause a change in the color that we measure or observe. This may explain why there are so many different colors in the stars that are being studied. The coolest stars are the red stars and their temperature is around 3,000 degrees C. Articles >> Why are stars different colors? Throughout history mankind has gazed up at the stars in awe and wonder. To the naked eye, most of the stars appear white. As the light from the stars comes through the earth's atmosphere, they appear to be twinkling. Until about two hundred years ago, everyone that studied the stars thought that all stars were white. This makes the cooler stars appear red and the stars with the higher temperatures appear blue or white. From cool to hot, the colors can appear red, orange, yellow, green and blue. If you remember the colors of the rainbow, you will see that these are in the same order. Red giants such as Betelgeuse are not actually that red in colour. If you look at the colour in table 4.3 above you can see that its actual colour would be more orange than true red. A small group of stars do, however, appear deep red. These are the carbon stars such as 19 or TX Piscium. A starfield in the region of Sagittarius showing stars of different colours. 1 Stellar Colours Human Vision. Interstellar Reddening and Extinction. 2 Measuring Colour - Colour Index Colour Index Problems. 3 Filters in Astronomy. However, idiochromatic gemstones are rare. Most gemstones are allochromatic, meaning that they are colored by impurities or trace elements in their crystal structure. For example, pure corundum is colorless. But corundum is typically red when traces of chromium are present and blue when there are traces of titanium. One thing you will notice from this list is that the relationship between chemical impurity and gemstone color is not a simple one. In some cases, a similar color can result from different trace elements; the green of an emerald can be the result of chromium or vanadium (or both). In other cases, a single trace element can produce different colors in different gem varieties. Thus chromium will produce a green color in emerald, but result in a red color in corundum. The colour of a star is primarily a function of its effective temperature. You should recall that a star approximates the behaviour of a black body radiator. As a black body gets hotter its colour changes. If you were to heat a solid shot put it would first emit radiation in the infrared region. Query: how do stars get their color

SOLUTION: The colour of a star is primarily a function of its effective temperature. You should recall that a star approximates the behaviour of a black body radiator. As a black body gets hotter its colour changes.
