More massive stars usually appear brighter, therefore bluer. Less massive being redder, and yellow in the middle. I could be wrong.
red
The color of a star is related with the wavelength of the light observed. Wien's Law states that: Peak Wavelength x Surface Temperature = 2.898x10-3 Peak Wavelength is the wavelength of the highest intensity light coming from a star.
The fate of a star depends not so much on its size (diameter), but on its mass.Low-mass stars (up to about 1.4 times the mass of our Sun) will become white dwarves. Above that, and the star will become a neutron star. Somewhere between 2-3 solar masses another limit is reached, where a neutron star isn't stable; instead, the star becomes a black hole. The masses mentioned refer to the mass that remains once the star runs out of energy.
Surface Temperature, and mass.
Think of a black hole like the neutron star's big brother. When a star reaches the end of its life, it blows off its outer layer in a supernova and leaves behind a stellar remnant. The mass of the star, during its life, determines what is left behind by its death. For relatively low mass stars (such as our own star), the remnant is a white dwarf. Get much larger than about 1.4 times our own star's mass and you end up with a neutron star. The exact upper mass limit for neutron star formation isn't known for certain, but the estimate is something between 2 and 3 times our own star's mass. Above that, and the remnant core collapses into a black hole.
The more mass a star has the less time it has to live or "be a star." The less mass a star has the longer it has to live.
well it depends on how fat you are.

There is no simple relation. The color does not depend only on the mass. The same star can change color, without a significant change in mass. For example, our Sun is currently yellow; in a few billion years, it is expected to get much larger, becoming a red giant. However, if we limit the sample of stars to those on the "main sequence" of the "HR diagram", there is something of a relation between mass and color. The most massive stars are blue or white. They are also hottest and most luminous. The least massive are the red dwarf stars, which are relatively cool and dim. Our Sun, which is a "main sequence" star at present, is somewhere in between those extremes. (There is a strong relationship between mass and luminosity for main sequence stars. The HR diagram, of course, shows there is a relationship between luminosity and color for the main sequence stars.)
So in terms of of color red is cool, yellow is medium, blue-violet is hot.
The relationship is that the color is an indication of the star's surface temperature. For example, red stars are cooler, while blue stars are hotter. You can find more details in the Wikipedia article "Stellar classification".

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.
The color of a star is related with the wavelength of the light observed. Wien's Law states that: Peak Wavelength x Surface Temperature = 2.898x10-3 Peak Wavelength is the wavelength of the highest intensity light coming from a star.
Blue stars are the hottest, and red stars the coolest. Our sun is orangey, so it's kinda in between blue (hot) and red (cool).
The mass could either be a red giant or a super giant, they both evolve into different ways, after a star runs out of fuel, it becomes a white dwarf, a neutron star, or a black hole.
