please take a look at
http://curious.astro.cornell.edu/stars.php
Stars and colours vary in temp from
80.000deg k over 8 main bands down to 2000-3000 deg k
our sun is 5800deg k and is yellow.
The web site give other main details. One point that is hard to accept is that some stars are massive and can be as big as our solar system!!!!!!!
