It varies, depending on the stage of the star's development.
The temperature affects the color of a star.
The most massive main sequence stars are typically blue in color. These stars are classified as O-type stars, characterized by their high temperatures and luminosities. Their intense heat causes them to emit light primarily in the blue and ultraviolet spectrum. Examples include stars like Zeta Ophiuchi and the stars in the Pleiades cluster.
Depending on the mass of whatever is left over of a star, it can turn into a white dwarf, a neutron star, or - in the case of the most massive stars - a black hole.
The color of a star is related to its temperature. More massive stars are typically hotter and appear bluer, while less massive stars are cooler and appear redder. This relationship is described by Wien's law, which states that hotter objects emit more blue light and cooler objects emit more red light.
The sun
its a blue color
The most massive type of main sequence star on the HR diagram would be indicated by the main sequence area at the top left of the HR diagram, which would be blue or violet in color. Zeta Puppis is an example of such a star. It comes in at 40 solar masses. It is classified as a type "O" star.
Massive stars can appear in a range of colors depending on their surface temperature. They can range from blue (hottest) to white, yellow, orange, and red (coolest). The color of a massive star can provide clues about its temperature and stage of life.
Generally, the more massive a star is, the more luminous they are. The most luminous stars appear blue.
Red
The most massive main sequence stars are typically blue in color, due to their high surface temperatures. These stars are known as O-type stars and can be tens of times more massive than the Sun.

Look in the link below for a table of the most massive stars.
Within a binary star system, the most massive star is called the primary star, whereas the least massive star is called the secondary star. See related question.
No. The most massive stars have the shortest lifespans.
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.
