Generally, yes. For stars on the main sequence, meaning that they fuse hydrogen at their cores, mass, size, color, brightness, and temperature are all closely related. More massive stars are larger, brighter and hotter than less massive ones. The least massive stars are red. As you go to more massive stars color changes to orange, then yellow, then white, and finally to blue for the most massive stars.
A star's color is related to its surface temperature.
the color of altair is yellowish-whaite ...
No it depends on its temperature.
A white dwarf star is created after a nebula and the black dwarf star is created after a nova
The color of a star is mainly related to the star's surface temperature. This is only remotely related to the star's mass; for example, high-mass stars can either be very hot (blue) or not-so-hot (red), depending on the phase in the star's life.
