Q: Answer-The different colours of different stars are due to the variation of –

Shortly after blackbody radiation was understood, it was noticed that the spectra of stars look extremely similar to blackbody radiation curves of various temperatures, rangingfroma few thousand Kelvin to 50,000 Kelvin. The obvious conclusion is that stars are similar to blackbodies, and that the colour variationofstarsisadirectconsequenceoftheir surface temperatures.
